I agree with the consensus of FoD. It's really comfy for combos, The horizontal isn't too large to make recovery impossible, and the ceiling is at a good spot as well.
For me, it is mostly situation where I like to go, depending on who I fight. I actually like FD as a player, but I think there are many other characters, such as the spacies or Marth, who could take advantage of G&W more than G&W on them. Smashville is a little more in my favor, but sort of the same story.
Personally, I like Yoshi's Story simply because of all the sweetspotting ledge practice I've had makes me feel comfortable in recovering, while the tiny spaces work to my advantage.
Pokemon Stadium 2 and Metal Cap Cavern are also ones I favor. I appreciate some ledges, like 1 or 2 on stage, but not like Battlefield with multiple ledges. I want the few in case for follow up areal combos, but I don't like stages where there are too many ledges where when you are high up your opponent can reach you so easily. You can take advantage of the small spaces in Metal Cap for stage control, but also utilize the low floor to easily sweetspot back to ledge.
I can't really say I like Skyworld because of how often I accidentally miss the ledge and hit my head on the floor. Same for Skyloft. Another thing about Skyloft is also how your angle on the stairs often messes with the direction of your dtilt and your bacon. Strangely I don't have this issue with Metal Cap.
