The Stages good for Pit completely rely on th type of fighter you are.
If you like to Spam, Loop, or Swarm Arrows, then you'll love Final Destination. However if you're a speedy little bugger who platform cancels and Platform Wing Cancels to increase Pit's speed and aerial maneuverability, then Final Destination sucks for you. In contrast, Lylat Cruise is AMAZING for Pit if you like to platform cancel and the such but don't rely heavily on arrows.
The trick is to have a very well rounded Pit. In doing so and being able to change your play style on a whim, you can take advantage of most stages.
