Compliling a not-so-big list of what has been voted. I had planned to go all 14 pages (i do 40 posts per page, not the forum default), but it got extremely boring.
ANYWAY, this tally is recorded up to post 160, and I had left out votes that were not clear, so it's a good rough estimate.

Staggering Results eh?
Stages I don't play on a lot.
Mushroomy Kingdom, Pirate Ship, Port Town Aero Dive, castle Siege, green greens
Stage I don't Like to play (with reason)
Mario Circuit - walk off's, doesn't feel like a stage.
Rumble Falls - I like this more than mario circuit actually, I'm okay with fighting on the go, but again whenever it speeds up you tend to be more concerned about not falling behind.
Bridge of Eldin - walk off's, Large and is nothing more than a big platform, it's a cool idea for a fighting ground, myabe if it was so **** big.
Distant Planet - Weirdest layout for a fighting ground, a walk off on one side and a small platform in the middle.
Luigi's Mansion - I like to jump around, having a tiny roof ain't cool
New Pork City - When I first played this game it was with 3 other people with items, i was cool with this until i started playing more competitively.
Summit - Floating scene = boring, layout ain't that cool, no ledges, everyone slides except for IC, and there's very no escape from the fish for heavyweights.
Green hill zone - i never liked sonic that much. walk-off's and those pinwheel hazrds warp the playstyle of the map.
Temple - With many people, big maps with MANY different paths to get above or underground was cool, 1v1 wise, no.
Yoshi's Island Melee - walk off one side, falling another, just strange to me.
Onett - Although there's walk-off's, the way houses are put near the edges kinda bring you towards the center is what makes it work for me, similar to FD where everytihng is central. However random vehicles hit you even though you're not on the road.
big Blue - only sonic can keep up on the road, sadly cf can't keep up even with bunny hood. But it's not that i dont like it for that reason, it's because if someone hits you with something of small knock back but enough htistun u get pushed onto the road and die. a good example is G&W or jigglypuff's dsmash, send you right onto the road.
brinstar - i forget about this stage often, it's cool actualy, looks like a normal stage at the very least so i dont mind the rising lava too much. What I REALLY don't like is he tumour-like joint that holds the stage together, you can't walk across without struggling or hopping.
to solve some of the issues to make certain stages playable, Freeze Them with Level Freezer. I've frozen several stages making them more playable, as it becomes a plain motionless platform with zero hazards. Here is some possible outcomes, though I currently only have corneria, pictochat and poke 2 frozen.
-Bridge of Eldin (Basically FD with walk-off's)
-Delfino Plaza (plays like Battlefield, but I recently unfroze this)
-Norfair (I recently unfroze it)
-Frigate Orpheon (I never froze this stage)
-Pokemon Stadium 2 (no floatiness, treadmills or sliding on ice)
-Spear Pillar (Double Platform with no random hazards)
-Port Town Aero Dive (A platform with no Ledges)
-Castle Siege (Castle Top only)
-Halberd (fighting on the ground only, no platform or deck)
-Warioware (plays like a neutral)
-Pictochat (absolute neutral, i encourage many people to do this too)
-Shadow Moses (plays like normal, except walls won't respawn now), making a Bridge of Eldin with platforms.
-Jungle Japes (No KlapTraps, and rushing water animation, however you'll still be pushed by water)
-Rumble Falls (The main ground with many platforms)
-Rainbow Cruise (Fighting only takes place on the ship)
-Corneria (No Arwing and Star Fox Lasers)
-Green Greens (No block spawning after the match starts, i recently unfroze this)
-Big Blue (unsure never tried, but my guess is that the ships stop and you can actually fight on the road, be a REAL street fighter lol)
-Brinstar (unsure, never tried, but I guess breaking the joints won't heal itself nor will the lava rise)
-Pokemon Stadium 1 (No activity, I unfroze this recently)
-Luigi's Mansion (once the house is broken i don't think the house will respawn, that or just get the deadlands mansion code)
