Based on what I've read on SSB4 Sonic..

Hello.

Based on what I've read the general changes to Sonic are:
-feeling faster (partially due to game speed)
-more KO options
-can KO at lower %s compared to Brawl
-Different Down A Smash
-Side B being quite improved

Besides those, does Sonic generally feel the same in terms of playstyle and matchups?

Won't know until we get our hands on him. I'm sure his off stage game play will be great but as far as match ups I couldn't tell you.
