I wanna pick my own previously established neutral stages to rank! Why do I have to use yours! Gosh you're such a control freak!
They're not his. They're the ones officially chosen by the competitive smash community (mostly the SBR, I think). Although there are disputes as to what other stages should be neutral or not, these are the current 5 that are deemed neutral.
Ranked based on neutrality:
1.) Battlefield (Decently sized with reasonable platforms and no outstandingly ridiculous features)
2.) Smashville (Behind batlefield due to it's smaller size. Favors heavier characters over lighter ones)
3.) Lylat Cruise (Bent edges and tilting affect horizontal spam, such as lasers. Also, the three platforms are placed less ideally than BF's)
4.) Final Destination (not because it sucks, which I believe it does, but due to its lack of neutrality. It's lack of platforms encourages spam like nothing else. DO NOT PLAY A FALCO ON FD. The lips on the edge destroy certain recoverys while helping others. Metaknight's up-b against the lip autosnaps to the ledge, while spacies get owned.)
5.) Yoshi's Island (Small. Stupid platform in the middle that stops projectiles going into it because it tilts. Support ghost that saves people randomly. A proper edgeguard could mean nothing if the other person is just saved by the support ghost)
Ranked based on self-preference:
1.) Smashville
2.) Lylat
3.) BF
4.) FD
5.) Yoshi's
