In this, since the game is less boost-boost-SONICBOOM all the time, and enemies could be coming at you from a variety of different directions, the standard jump attack is more useful, but it's only rolled up at a certain distance from where it started. It's uncurled for a moment as it ascends, and more annoyingly at times, uncurls when it drops beneath a certain height—you can never jump-attack anything that's at a lower height than the low-jump, even if you're jumping at a lower platform.
Thus, if a Spiny is on the ground and you wish to kill it, jumping is suicide. Boost or slide.
Wrong.
Personally, I like the little uncurled hop that Sonic can do in Unleashed and Colors. I have no issue with it. Reminds me a bit of the uncurled Sonic 1 jump.

You're right that Sonic also uncurls in Colors during the descent phase of a jump. But I already told you how to avoid this
here!
Again:
Sonic does NOT uncurl if you KEEP THE BUTTON PRESSED.Jumping on badniks the oldschool way can be quite fun and it's perfectly possible in 2D sections, but of course it would require insane skills in 3D sections, so the homing attack is still preferable there.
Check this out, for example.
