Most of Pit match up are 50-50, and he has no unbeatable match ups.
Every players have differents opinion on who Pit looses to or not.

For picking a secondary
It comes down to what characters cover MUs that you're personnally uncomfortable with
Since Pit can do pretty much any MU with enough dedication towards learning it
Personally don't suggest Marth/Corrin as secondaries, since they share a lot of flaws with Pit
Cloud, Mario, Diddy, Mewtwo come to mind

I would add that until you AT LEAST get out of pools frequently, you shouldn't pick a secondary. As if you are struggling against precise characters is due to flaws in your gameplay (cannot deal with projectile, aggressive style...).
