(Mods, I will remove this if needs to go to a different section).
Just my thoughts on legal stages!
Legal:
Battlefield (Simple, easy layout)
Final destination (Flat)
Town and City (Platforms move, but not disruptive)
Smashville (Singular floating platform makes it unique)
Lyat cruise (Simple, The platform rotating isn't bad)
Counterpicks:
Delfino Plaza (Transforming, no hazards)
Hallberd (I'm afraid i can't do that Dave. Sorry, that joke gets old. This stage is nice, stage hazards, while here, are easily avoidable.)
Debatable:
TEAMS ONLY (It would be to campy 1v1s) Big Battlefield (Is it too big? I have literally NO idea when it comes to Big battlefield.
All
Ω Stages. (I'm going to be honest here. I don't know about the final destination forms. Do They have the same blast zones? Should you be able to go under them? I really don't know.)
PilotWings (I Don't know if this should be legal for teams, 1v1s, or both. The Tilting platforms, and the sometimes no kill floor sometimes present a problem.)
Miiverse (Of course, at the time of this writing, Miiverse hasn't been released. Will the drawings in the background be distracting? Or will the battlefield similarities pay off?)
Kongo Jungle 64. (Strangely, a 8 player smash choice, Kongo jungle, is interesting. personally, I think it's bigger than it first appears. Teams?)
Wrecking Crew (Bombs, and it's too tall.) UPDATE. HavocThunder has some good points about this stage. Check comments.
Wuhu Island (Cheap KOs,and it gets in the way. But it's kindof like Delfino Plaza. This glitch,

Castle Siege (Nearly legal in brawl, not that bad. Stage Transformations can turn this into a walk off, and kill you easily.)
Skyloft (Transforming stage with some Hazards. It can turn into a walk-off, and it can be a huge stage at times.)
TEAMS ONLY Windy Hill Zone (I don't know, zero hazards, it's big, great for 8 player teams; this might be fondly one remembered stage)
Banned:
Jungle Hijinks (It's too big! The pillars present problems, and the barrels are campy.)
Duck Hunt (Too big, weird platforms, and you can hide behind grass.)
Mario Circuit (Brawl) (Walk Off, disruptive hazards)
Mario Circuit (Cars are disruptive stage hazards, No kill, well, everything. walls, and ceiling.)
Coliseum (Walk-Off)
Gamer (Disruptive stage hazard. MOOOOM!!!!!!)
Dr. Wily's castle (Stage boss, Yellow Devil)
Palutena's Temple (Seriously? Do you want a tournament to last for 10 hours!!!!!!!????? No.)
Pac-Land (Side Scrolling)
The Great Cave Offensive (It's too big!)
Garden of Hope (Disruptive hazards, and it's too Big.)
Orbital Gate Assault (As we know from one Pic of the day, this stage took a year to make. Well, to that I say... BANNED!)
Pryrosphere (Because Ridley didn't make it in, he had to get mad, and ruin this perfectly good stage).
Boxing Ring (Walk-Off)
Kalos Pokemon League (Swords, Fire, Metal and Disruptive water 7.8)
Mario Galaxy (Walk-off)
Mushroom Kingdom U (Nabbit is extremely annoying, causing early kills, and cramping the game.)
Wii Fit Studio (Walk-Off)
Gaur Plain (HEY HEY! It's too Big, and Metal Face.)
Woolly World (Walk-off, and it's too big.)
75m (Disruptive hazards, and too big.)
Onett (Too big, and stage hazards. Cars.)
Port Town Areo Dive (No kill floor, and cars.)
Flat Zone X (Walk-Off)
Skyworld (Destroyable terrain, and, like kongo jungle, It's much bigger than it first appears. Heck, it's even a 6 player smash stage!)
Luigi's Mansion (Destroyable terrain, and it's too big!)
Norfair (Boiling Hot Magma. Get it?)
Pokémon Stadium 2 (It can make characters too light, and it's slippery at times.)
Temple (Too big!)
Bidge of Eldin (Walk-off)
Yoshi's Island (Stupid yellow platforms, and it's too big).
