Smash Cadet
so I've come to the conclusion that it doesn't matter what move you do to cancel your momentum. if you just DI it correctly, any move will work. the only time it matters is when your DI fails and you go more horizontal then up. then you should do bair or airdodge. I've just been in training mode trying to survive smashes lol so I was testing what works best and that's what I found. also I find it a lot quicker to spam A for your aerial anyway instead of using the C stick. this may or may not be news to some of you, but just thought I'd share.
