About Totems and EVs, firstly, would you have the source for that, as it is something that can't be checked in game? But I'm pretty sure B2W2 Gym Leaders and E4 teams also have good stats too although I don't have any sources either, just intuition.
Secondly, the thing is, despite the stat boost and all, they still don't have that good moves, items nor AI, so they're not that hard. Talking about AI only, have you ever seen how Necrozma (theoretically the toughest challenge in the game) reacts to a Zoroark?

Besides the difference from Exp Share and also other small things (such as gen 7 handhold, since difficulty isn't just about battle, or the Z-moves).
And on top of that, B2W2 is even more difficult for many more reasons. Like PWT being harder than Agency.
And have you ever seen the E4 rematch team?
Overall, even with all that, they're pretty similar in difficulty, since B2W2 isn't that much harder. But B2W2 Challenge mode is harder, that's the truth.
Posting a thousand times the opposite will not make it truth
