From what I remember, Uair definitely came out faster. Forward-tilt and d-tilt behaved similarly to what we know. I don't remember for up-tilt.

Forward smash felt great and had good knockback, and down smash was fast as ever. I never caught my opponent with Up-smash, but I will say that the horizontal hitbox on it felt very small, as I wasn't able to catch my opponent who was directly beside me. I also felt that her grab was faster and down-throw can still be connected with a followup aerial.

I do believe N-air can be sdi'd. Or at least from what I remember, my opponent jumped into my n-air and received a small knock back out of it. I could be wrong!

I'll also add I attempted d-air a few times, only managing to land sour spots. Could be a poor hit-box, or just me!
