I'm guessing most reviewers are probably just trying a couple games on the vita after reviewing the PS3 version but I still find it odd that I've seen the same specific complaint that is addressed in the game.

Pulse pitching works fine on the Vita version. The review complains that they haven't done anything to make pitching easier on the Vita version but they have. Yes using the sticks to aim pitches sucks but they allow you to aim with the touchscreen which makes aiming quite a bit easier than on the PS3 version. There's also an option to turn on a border around the pulse indicator if you're having trouble seeing it.
