I don't agree with the notion that "they're so overpowered you shouldn't use them." The main game is so easy it really doesn't matter what you use. I've played through entire games without using a legendary and while using one, and there was little to no difference in how easy the game was. I'm not trying to be "edgy" or anything, I just don't understand how they make the game any easier than it already is.
In-game "competitive" things like the Battle Subway / whatever already have the majority of the legendaries banned, so it's not like you can use them there to make that easier. (Even if you could, the game would create teams to work around them, but that's another matter.)
For competitive purposes, if the tier allows them then I use them if they fit the team I'm building. I like to build strange teams, though, so it's not often they find a spot. For battles against friends, if they agree to using them then it's fine.
