Any stages that one can phase through (Delfino, Halberd, Mute City, etc.) make it impossible for Zelda to snap to the ledge when teleporting parallel to it meaning she has to limit how she recovers which is bad in and of itself. I always strike Delfino as often as possible, not so much Halberd because the terrible section of the stage only lasts for about half the time the match should be taking place as opposed to Delfino. Another reason I don't strike Halberd is because I prefer striking Lylat Cruise. Lylat should speak for itself. Can't snap to a ledge that is able to dodge your snap. I'm also looking at you Pilotwings... I've actually been considering whether or not striking Delfino and Halberd is even a good idea though because of their low ceilings which work in our favor with the elevator (granted they tend to work in the opponent's favor too... hoo hah anyone?). Generally, I'm fine with all the other legal/counterpick stages though I'm not a huge fan of Duck Hunt's high ceiling and that damn dog that only seems to want to lift me up when I'm about to punish the opponent.
As for omega stages, most of them are fine except for a select few with the weirdest architecture on the bottom like Bridge of Eldin that was mentioned earlier. I believe Pyrosphere works similarly.
