It's surprising how high people put Pits. I'd personally say they are in mid tier somewhere as they lack the frame data to be in high tier. I guess Nairo and earth help Pits to maintain their position.
Routa said it well, his frame data is by no means underwhelming and he's above average in just about everything else. Add onto that the fact that he doesn't have any unwinnable matchups (I'd say the only noticeably disadvantaged matchups are ZSS and
maybe Sonic, though others disagree with me on that, with Sheik, Mario, Fox and MK being the only top-tier matchups that are otherwise inconvenient), is essentially immune to patches (for the most part; Sakurai strongly implied that he doesn't want to change Pit too much, which is why it was especially surprising for Dark Pit to get that Electroshock buff), has consistent tournament placings (he doesn't turn up often, but the players that do tend to use him at the top are very good, especially Nairo and Earth) and doesn't seem to have much in the way of competition (again, there's nobody that threatens to bump him out of bracket at the CSS, he's never overtly threatened with failure from the get-go).
The other thing I'd say is that, to be a good character, you need to have
options. The more options you have in any situation, and the more viable those options are, the better you can deal with what comes your way. Pit may not have Sheik or ZSS tier frame data, but most of his moves have their place in his kit (at most I can name a very small handful of moves that I never use, and even they have their niche in certain respects). I don't think a good Pit should ever think, "Oh, damn, X used this move, there's no way I can react to that"; unless the opponent's using a move that everybody, by definition, has difficulty with, you should never feel helpless.
This is a big reason why he's so good at reflecting a player's fundamentals: he has enough options, and more importantly enough
good options, to cover his bases well in any matchup. Weaker characters either don't have that many options in the first place, or the options that they do have don't yield the same reward as stronger characters, and that makes it easier for them to be put in a state of disadvantage which they cannot recover from. Pit may not dominate as much as other top characters, and that means he'll never be a top-tier himself, but he can at least expect to react well to most kinds of pressure and mould to fit the player's gameplan. That's why a low or mid-level Pit isn't especially impressive, but a top-level Pit can really stand out: you're free to let your knowledge of the game and its mechanics do their thing, rather than bottlenecking yourself into a certain handful of moves that causes your entire gameplan to disintegrate if countered. Give it a while, see if more good players pick him up. Then I think we'll see some interesting developments for the angels.
teleport i think the reason his is so wonky can largely be attributed to one factor:
