it's not a "bullshit argument". the point is that the other megas i mentioned are extremely exclusive and straight out best at what they do (with the exception of mega aero who might be relatively outclassed by mew). now, lets compare manectric to other electric types:
mega manectric vs magnezone:
mega manectric loses in
-specs magnezone is 2x stronger
-it has a much worse typing
-it has no means of beating dominant special walls like florges, latias, umbreon and snorlax
-it's 25% less physically bulky EVEN after factoring intimidate
-it's 10% less specially bulky
-it's walled by swampert, gastrodon, quagsire, etc if using hp ice, or every other dragon if using hp grass
-magnezone resists stealth rock and is immune to toxic/toxic spikes
-magnezone doesn't consume a mega slot
magnezone loses in:
-manectric's speed gets a jump in gligar, adamant aerodactyl, mega houndoom, mienshao, heracross, zygarde and chandelure and those are the only pokemon that magnezone would like to outspeed.
-overheat/flamethrower lets it get past... ferroseed, steelix, opposing magnezone and thats it
-it can survive random earthquakes i guess?
-???
mega manectric vs raikou
mega manectric loses in:
-raikou can use leftovers, choice specs, choice scarf, life orb
-LO raikou is 17% stronger
-raikou is 28% more specially bulky
-raikou has calm mind
-raikou can setup/defeat florges, latias, suicune, etc.
-raikou doesn't consume a mega slot
raikou loses in
-manectric gets a speed jump on adamant aerodactyl, and thats it
-manectric is 40% physically bulkier IF it has used intimidate
-overheat/flamethrower lets it get past... again, ferroseed, steelix, opposing magnezone and it hits celebi better i guess?
and manectric is A, while raikou is B+
The magnezone/manectric comparison is flawed with them having completely different roles. Regarding bulk- the overwhelming majority of the time mega manectric can avoid getting hit whatsoever, allowing it to deal free damage that magnezone can never do. Similarly while magnezone might hit twice as hard, it has to switch in and get hit twice first due to pathetic speed before it can do anything to basically anyone. Saying that magnezone only would like to outspeed 7 pokemon is a really bizarre argument seeings as later in the match magnezone doesnt offer anywhere near the same cleanup ability as manectric, which is perhaps the nicest combination of speed, coverage and power for cleanup in uu at the moment.
Fire type coverage hits about 5 pokemon in the S-A tiers, which is definitely not as negligible as you are making out... Im not gunna retype the whole post but comparing the two is basically worthless anyway seeings as Manectric is a fast electric type revenge killer, scout and cleanup and magnezone is a slow as balls wallbreaker.
People seem to have this weird assumption that you have to run max speed on mega manectric too. 96 speed with a timid nature lets you outspeed base 115s, giving you the option of a 160hp/252spa/96speed spread, which would both allow you to outspeed timid raikou, hit harder, and have both way higher physical bulk as well as closer special bulk. Alternatively you can run 32hp/252spa/220 speed with a modest nature on mega manectric, and still outspeed all those base 115s, while gaining access to a special attack which is comparable to LO raikou (407 compared to raikou's equivalent 427) without any issues of hampering you own bulk due to recoil. Also mega manectric coverage moves obviously outdamage raikou's by a huge margin.
Of course raikou also has the issue of having to run rash nature if he wants aura sphere, which is his only worthwhile coverage move- apart from hidden power.
Mega manectric outperforms rash raikou pretty heavily too. With rash nature raikou fails to outspeed positive base 101 and higher, which means it misses out on a lot.
Even with timid raikou, his speed is more of an issue than you are making out, and doesnt allow him to deal with the same threats that mega manectric can. Timid raikou is speed tying with dangerous pokemon such as mega absol, azelf and houndoom, and is outsped by hawlucha who proceeds to smack him in the face for up to 78%.. Timid raikou can't catch tornadus-T and takes a pretty surprising 30% maximum from a u-turn, meaning it can even be cleaned up relatively easily by tornadus-t later with heat wave doing 44% maximum and focus blast doing 55% maximum. Similarly for crobat, raikou can never catch the bat and he can shave off 25% with every u-turn. Mega manectric can deal with all of these pokemon easily. I feel like you really made an effort to glaze over mega manectrics several positive points?..
And its great that raikou has calm mind, except the weakness of hidden power ice is going to hurt him as a sweeper, and not to mention that pure electric typing and weak defense is hardly ideal for a calm mind user- you could be using suicune's far superior pure water typing, or latios who can actually heal himself and can hit opponents on their defense stat, as well as having a dual stab to play with. I think raikou's place in B+ is justified by that. Its a good pokemon but its outclassed in its individual roles, despite being quite good all round.
Meanwhile, mega manectric actually excels highly at its niche role- which is not to be an electric type, but to be a scout, revenge killer and cleanup.
Also, intimidate is a perfectly reliable defense boost for mega manectric's role, considering it is mainly going to be using volt switch. That defense boost stays up most of the time, and has the added benefits of "boosting" allied pokemon's defense if you switch out and they stay in.
