Seriously though guys, this is the case with every Pokemon ever. It's akin to asking what the best Dragonite set is.
This is not true. What's the best set for ditto?

There should really be a pure Expert Belt set, as it is one of the most effective lures out there, and a pretty destructive set in general when used correctly. When i say Expert Belt i mean U-turn, Ice Beam, Thunderbolt, Flamethrower / Bug Buzz / Flash Cannon.
Are you joking? Leftovers ditto is strictly inferior to Scarf Ditto. The whole point of ditto is to revenge kill. Leftover ditto is just bad... I don't know of anyone that's ever run that. Ditto is too frail anyways to run leftovers correctly. Hell even Smogon agrees with me.Scarf Ditto is best against offense, Leftovers Ditto is best against more defensive teams, and pretty much anything else on Ditto is either for bluffing or trying to find a balance.
Not seeing your point. Yes, I know what you mean.
Focus Sash Genesect is a really inconsistent lead from my experiences with it. It's really good against opposing Genesect while you cant keep it around for later if you have a spinner alongside it but you do miss the speed that Scarf / Rock Polish sets bring. It was very effective in Dream World with Chandelure everywhere as well as Genesect lead matchups against eachother, but I really haven't had much success with it in B/W2, namely for the fact that the metagame really isn't as offensive as Dream World as there's not a lot that commonly brings Genesect down to it's Sash, meaning you can often have matches where you essentially have no Item just because you're reliant on getting OHKO'd. All of these Genesect sets have their own merit individually, but I'm very interested to hear about people's experiences with Choice Specs Genesect, as it's pretty much the only set I haven't used. Also for the Choice Band set, I'd definitely replace Flamethrower for Zen Headbutt or even Quick Attack. U-Turn still 2HKOs Ferrothorn without an atk boost from Download, while you shouldn't need to compromise your EVs to hit something that Genesect can break through otherwise.
As for my favourite Genesect set, it differs between Scarf and Expert Belt, while Rock Polish is still incredible on it's own. Honestly, you really should include an Expert Belt set with U-Turn, Flamethrower, Ice Beam and Giga Drain / Thunderbolt as that is the best set for Expert Belt imo as you can actually bluff a Choice item constantly thanks to U-Turn. Giga Drain on Genesect is excellent, especially on the Rock Polish sets. Some people think Genesect's weakness is hazards, whereas Giga Drain allows Genesect to regain some health as it is sweeping keeping it healthy while also allowing Genesect to hit a lot of it's main offensive checks a lot harder, namely Terrakion, Keldeo, Mamoswine and Rotom-W. As for the Life Orb sets, I'd strongly urge you to not use Life Orb on any Genesect set. While the extra power is appreciated, you can run the coverage to hit everything hard lessening the need for Life Orb while still not revealing your item. I think the scariest thing about Genesect is the sheer versatility of it, and that to deal with it you really need to scout the set beforehand. Life Orb gives this away on all of your sets, meaning you really only get one hit off before your opponent knows your set, whereas Scarf / Focus Sash sets can do this many times throughout a match.
Throwing my support behind LO RP Genesect like lots of others. It is kind of ridiculous how much of the metagame it can set up on and how powerful it is. If it manages a +1 boost in Sp Attk it can really power through a lot of its common checks like Terrakion/Rotom-W. I would say its next best set is an Expert Belt set with U-Turn / Ice Beam / Thunderbolt / Flamethrower. While Focus Sash works most of the time, I would agree with Jimbon that it can be incredibly inconsistent and Expert Belt serves more average use.
While Choice Scarf is its most common set I find it to be an incredible waste of potential and if I do run a Choice Scarf Genesect I often find myself needing to run a secondary Scarfer (Scarf Keldeo and co are way too common). Although it does need to be noted that these Scarfers really rose in popularity due to Choice Scarf Genesect, so take that as you will.
