1. Have you never played a good campy fox? There's no way to shut down proper camping without leaving yourself open at some point, and all the while you're taking damage. The ability to safely and effectively laser camp is a huge advantage for fox and thus a huge disadvantage for Ganon on DL. There actually ARE ways to deal with fox pressure. But the key is that fox can effectively execute either macro strat on DL and only one of them on YS.
2. I never claimed you said anything about survivability. I was listing reasons why YS is a better stage for Ganon vs fox, and this is a good reason.
3. The point is that one good oos option leading to a hit or even a stray hit almost always yields and edgeguard opportunity on YS, but much more rarely on DL. KO opportunities are much easier to obtain.
4. On DL, fox can literally keep distance and laser your ledge options. He has to be ready for much more on YS. Retreating to ledge also is a soft counter to being cornered. Once you have ledge, they have to let you safely ledgehop since ledgehop jab and grab are INV. There is always holes in someone's ledge pressure. If they're positioned to cover almost everything, an empty RLD, a ledgehop into wd back to ledge, a ledgehop offstage retreating fair dj regrab ledge, or a tournament winner fadeback fair regrab ledge will bait them into leaving options uncovered and often leaves them vulnerable. Ganon's ledge options are great.
5. People miss those types of edgeguards all the time, and dropzone dair is underused, especially on YS, as it secures the KO before you allow a situation to manifest where there is more room for error. As far as tilts/jabs, watch linguini vs slox at the 0:30 mark, dropzone dair would've been a good option in that scenario and a lot better on YS.
6. I don't agree. DL has room for chaingrabbing, NIL shenanigans, and only a tad more survivability. It's rarely good to play MORE neutral with a character that clearly destroys you in the neutral game department.
I agree that whatever stage you play best on matters a lot, and also counterpicking is much more complex than simply choosing what stage is best on paper. I'm just saying, YS is significantly better on paper.
