I think it looks like physics are not good mostly because of poor animations (I know, it sounds a bit crazy, but hey), so I personally think you should complete all the animation work before deciding to do some major changes to physics, if you'll ever going to make such decision.
But IMO you should make Sonic response and react a bit faster, and give player a bit more control of his movement – UT2004 version also kinda suffered from it, the character wasn't always easy to control. You should look over how it is done in Sonic Adventure – Sonic responses at the right time, does everything good an' fast and you always know what to expect from him.
Hope that helps.
oh and i said earlier
>put the DoF farer from player
