I can't just list stages I like and dislike... I am very opinioned about them. So basically, here is a summary of the stages:
Battlefield - Like it, especially since ZSS is one of my mains.
FD - Hate the edges, it's smaller... it's an alright stage.
Delfino - I hate playing on this one for some reason. It's not bad, I just don't like it.
Luigi's Mansion - I like this one just because it's big, and it's pretty neutral.
Mushroomy Kingdom - Scrolling sucks, and I hate the low ceiling.
Mario Circuit - I'd like it a lot more without the cars. It's decent.
Rumble Falls - Sucks, obvious reasons
Bridge of Eldin - I liked this stage at first, but the bomb and hole just get too annoying. It's decent, not great.
Pirate Ship - Don't like it, a least favorite. Stupid cannonballs suck and if you opponent hits you into the front of the ship while you are trying to get on it's a free KO.
Norfair - I like it just for the Golden Sun song. Not a huge fan of the stage layout though. Lava is annoying.
Frigate Orpheon - Don't play on it much, but I personally don't mind it.
Yoshi Island - If it were bigger, I'd really like it. Way too small though.
Halberd - Too small a lot of the time and the low ceiling sucks for ZSS since she's light.
Lylat Cruise - Don't mind this one, kind of small, but other than that I like it.
Pokemon Stadium 2 - Sucks because of the new transformations. Too much interference.
Spear Pillar - Depends on the Pokemon. My brothers' favorite stage, so we end up on it fairly often.
- Purple dog thing I don't mind. It doesn't do much that gets in my way aside from the beam across the bottom part of the stage.
- Pink monster thing - HATE IT. Interferes way too much, I can play decently on backwards now, but I can't do the upside down.
- Other little one - Hate it too. Stupid boomerang thing does way too much damage and knockback, if it was weaker it wouldn't cause near as much trouble.
Port Town - It's alright. Better than Delfino in my opinion. Just don't like the cars in this one because they KO at such low percentages.
Castle Siege Part 1 - Too small, don't like it
Castle Siege Part 2 - Like it. Only downside is walk-off edges.
Castle Siege Part 3 - Again, a bit small, but it's more manageable than part 1.
Warioware - Hate the minigames, hate the music, hate the bonuses that sometimes it randomly doesn't give even if you complete the minigame
Distant Planet - I just suck at this stage for some reason, I hate it...
Smashville - I like this stage a lot other than the music and animation style. It's fun and easy to play on though.
New Pork City - TOO BIG, GAH. Another of my least favorite.
Summit - If the left side of the main platform extended farther to the left, and it wasn't icy, I could handle it even with the gravity changes and water. But...that's not the case.
Skyworld - Gimmicky stage. Easy to get spike KOs off the lower parts of the stage if the platforms are still there. I don't really like it much, but I can stand it.
75m - Hate the platform set up.
Mario Bros - Hate the borders and the monsters with massive knockback. Borders are the worst, I've "fallen off" before while attacking when I got up because part of my character went into the off screen part. No leniency at all, if you are at all in off the side of the screen, you die.
Flat Zone 2 - Better than Flat Zone 1, but it still not a good stage. Too much the Gas Station and Prison (?) parts are way too interfering.
Pictochat - Decent. I hate some of the drawings, but most don't interfere much.
Electroplankton - Oddly enough, I enjoy this one because I always win on it XD but everyone else hates it so I never get to play on it.
Shadow Moses Island - Decent... would be better if the walls were the only "Walls." You can't go over them and that is what ruins the stage for me, since that has saved my opponents numerous times.
Green Hill Zone - Don't like it. Just the set up and the falling blocks. If the you fell a bit slower when the blocks fell it would be better, but you just drop, fast.
Melee stages, only two that I like are Corneria (less intrusive this time it seems) and Pokemon Stadium.
