I don't recommend Delfino. To try and bthrow a Marth off the walk-off, you'd have to either pivot grab or shield grab, which means the Marth wasn't spacing correctly. Trying to do either could result in FF Fair -> DB4 Red or Fsmash and YOU end up getting killed instead. There's also the possibility of getting water spiked. If you're dumb enough, there's also dtilt lock on the walls.
Halberd's a better choice. During the flight, you may have to land camp a little, since the platform baits you to Marth's utilt, but when you get on the Halberd's deck, you have plenty of room to move around. The area underneath the ledge can also help with spring gimping if the Marth panics on recovery.
I probably have to play the matchup again, but while BF is Marth's best stage, I don't ever recall Sonic having too many troubles vs him there (but that's probably just me being biased because a lot of you bitch at BF all the time in general). In any case, it's probably ban worthy if you don't feel like you have a better choice or the simple fact that you'd want to ban Marth's best stage for assurance.
Lylat Cruise is give and take. Both of you can easily screw up your recovery, and both of you get messed up by ftilt. The only factor that might put this in Sonic's favor is that you can juggle better. Hyphen Smash/DACUS is also a plus.
Frigate is pretty cool. Take command of the left side of the stage on the first transformation, and you're already at an advantage. On the second transformation, the dip in the middle allows you a bit more comfort. Marth's tilts start from low to high, so you may find yourself getting "under" his attacks more often when approaching from that slant.
Final D is probably going to be banned by the opponent, but if you get a chance, you know what the deal is.
Pokemon Stadium 1 might work. I have no backing for that argument, but it's there for consideration. Same for Rainbow Cruise.
My opinion:
Ban - Battlefield
CP - Final Destination, Halberd, MAYBE Frigate.
