Spoilers ahead.
Sonic didn't seem to show many new feats himself, but his feat from the first movie got explained a bit more. His shockwave was described as traveling halfway across the galaxy. A single quill was enough to power a beacon that shot into space.
Super Sonic is probably Low 7-B for creating a storm. New powers include Flight, Light Manipulation, Creation (Created two chilidogs), Weather Manipulation (Created a storm), Explosion Manipulation (Said that physical contact with his Super Form would cause Tom to explode)
Tails can scale to Sonic minus speed, as he's shown to be physically comparable. His gadgets include;
•Laser gun
•Electric rope
•A boomerang that targets any hostile in the area
•An anti-gravity field
•Translator
Knuckles breaks apart a few boulders that would he worth calcing. 9-A for Sonic, Knuckles, and Tails is very realistic.
