It's just one of the best offensive threats in the tier. I personally prefer Boots Spin + 3 attacks as the best set, as I think it's the most splashable and with Focus Blast/Freeze-Dry can force out a lot of common rockers on top of still being a solid offensive threat. Nasty Plot sets are also dangerous late-game, as everyone knows, and choice sets can even be worthwhile on certain teams. So why don't I think this is S? I think ultimately, Mime just wants to do too much on its sets. Ice/Psychic/Fighting coverage is good, but the meta's adapting and now it really wants Shadow Ball. Except it doesn't really have the space for Shadow Ball, because it wants all of Ice STAB/Psychic/Focus Blast/Spin or NP/Shadow Ball on each of its sets, which it just can't feasibly do. The choice between Boots and Eviolite is tough as well. I feel like I've spent a lot of time talking down Mime, which is probably because everyone knows what it does anyways.

The only reason this isn't S Rank is because it's not really self-sufficient. It's the best offensive Pokemon in the tier when it gets on the field, the best revenge killer vs anything that isn't Scarf Gastly or Drakloak (and Drakloak can't OHKO it from full with the most common set), and it's capable of wearing down and breaking through its own checks given enough free turns, since none of them have recovery. The only thing it can't do is get on the field safely, so it more or less requires pivots to do that for it.

Slightly overlooked because of Gime in the tier, I feel. Sash sets have never really been better than they are right now, given that you can't just directly hit it despite its abysmal bulk for fear of retaliation. Other than that, Gime's access to Focus Blast is definitely a plus over Kadabra, but Kadabra's extra speed and one-shot ability to take any hit are still fantastic. Didn't really change much as a Pokemon.

Requires zero explanation, does what it always has and benefits hugely from both Golbat and Gabite's mere existence.

Gurdurr being more popular than Machoke actually made Tangela better, as now it can't just lose to a stray confusion hit and will nearly always outspeed Gurdurr by default. Other than that, mostly echoing Ho3n here except I actually do think the low SpD is a somewhat limiting factor, with pivot into a strong psychic being really easy to set up on Tang through stuff like Buzz, Thwackey, or even Defensive Wartortle.

Best blanket special check (as in, trying to check Gime/Kad/Tort/Buzz at once), spreads knock, and generally does ferro things. Has to watch out for stray Focus Blasts now, but can usually take one if it has to.
A:

Golbat's existence and ability to speedcreep it is pretty annoying, as while as Magmar being able to take a hit or two, but other than that it hasn't changed a whole lot. Band Sets are coming back a bit since pivoting into a psychic type deals with most of Thwackey's checks, but I still think Grassy Seed sets are solidly the best since Golbat can't take too much damage or it's suddenly unable to check it.

Underrated a bit imo, once the priority users/sash kad are gone it just flat-out wins against a lot of teams right now, and most teams only have one way to stop a Wartortle sweep. Spin is okay if your team really needs a spinner specifically since it continues to have literally no competition for that role, but smash sets are the real draw.

Took Machoke's slot on a lot of teams, although every team is prepared for fighting types and it wants way too many moves to fit, so its ability to actually get through its checks is pretty limited. Still great at spreading Knock and Defog is cute, plus its bulk and somewhat reliable recovery in drain punch help it vs offensive Pokemon if it can get in on them without taking too big a hit, so I can't knock it too hard.

Very good at keeping hazards off and keeping itself alive compared to last meta, as Gorsola is less common so it can go physdef. Its typing is also helpful vs Gime (less so Kadabra because Kadabra actually does run shadow ball commonly), which gives it more utility. I've been liking physdef resttalk as while as Nuzzle in general on more standard sets.

I feel like this is being underrated a bit, while it's obviously not the all-star wallbreaker it was last format it's still an invaluable pivot since nothing's actually immune to bug, making it still the best partner for stuff like Pikachu or Kadabra in terms of getting in defensive Pokemon that they can take advantage of. My personal favourite set for it is Scarf, as the extra speed really does help it and lets it run Assurance or other coverage to get around Corsolas or Drakloaks trying to stop it. In general I feel like Pivot teams, while no longer being the single best playstyle in NFE, are still very good and should be considered for more than they are.

way better in practice than on paper, this and Pika force a volt immunity (or otherwise very sturdy resist) onto practically every team, even if it has to rely on focus miss or toxic to actually break down its walls this gen.
A-

Hits very hard, spreads status well, and can even run taunt to mess with walls, but doesn't have much defensive utility outside of random flame body procs and, like gime, really hates having to pick between Eviolite and boots. I might be underrating it, but I feel like A- is really the best place for it right now.

Ferro's just better right now due to being able to do stuff on its switchins besides pivot or rest, but Klang's still a viable option as a blanket SpD wall. Shift Gear sets are okay, but you really want all the SpD you can have right now, which hurts them. If you need your blanket SpD option to pivot, this is your best choice, but on more teams you'll want Ferro.

TSpikes are incredible in this meta, so is being able to set them on Hattrem. Hates Golbat obviously, and the psychics but is otherwise just incredible at being a physical check to Gurdurr/Thwackey/Raboot. It is unfortunately pretty reliant on is Eviolite, moreso than a lot of other NFE walls due to having pretty middling stats, and it can get worn down pretty quickly.

Doesn't really check as much as it used to due to the more varied options for both physical and special walls, but it can still do both and just be really hard to kill. I've been toying around with a more offensive set abusing Hex so it's not so incredibly passive, to pretty decent results, but the main draw is definitely still its walling capabiliies.

spreading TSpikes, as previously mentioned, is extremely good right now, and Mareanie comes with Regenerator to fix Koffing's biggest issue. Haze is cool to stop Thwackey and Wartortle since none of them are really instantly threatening to it. However, it can't set them on Hattrem, which does hurt it somewhat, and it doesn't appreciate the new strong electric and psychic attackers all that much.

It's a nice offensive rocker and punishes Pikachu and Raboot better than Piloswine, which is enough to get it this high, but it has a harder time beating the tier's various removers and having to rely on EQ in a meta with Thwackey really isn't fun for it.

While Gurdurr does see more usage thanks to its higher bulk and attack (somewhat mitigated by the fact that Drain Punch doesn't hit very hard), Machoke is still a perfectly good option if your goal is to break open physical walls for other physically oriented breakers to abuse. DynamicPunch is still incredibly uncompetitive and it can let it get past stuff that Gurdurr can't if you get a confusion roll, but that's obviously not a certainty. I'll also still maintain that FO Machoke is better than FO Gurdurr due to the higher speed letting Machoke get the jump on more things, most notably slower variants of Tangela.
