*shrug* Use powers. They work much better anyways, thanks to augmenting system. The class features are just bonus. But yeah, Psionics does it better. The flavour...well, reflavour them if you must, but really, I don't see what's wrong with "mind magic" or "inner magic" (whereas arcane manipulates energy fields available and divine channels planar/natural [energy of the living] energies).
At first, Psionics felt weird to me, but now after using it for a while, I couldn't imagine playing D&D without them. It's mostly just that Psionics changes everything for the better. And the flavour problem is something you'll get over if you actually bother to learn the rules and use 'em - at least that's how it worked out for me and I can't see why you'd have any stronger reservations. Oh yeah, and Mind Flayers are 1000000 times cooler as Psions than Sorcerers.
EDIT: Oh, he linked Pyrokineticist. Meh class; I prefer true manifesting myself. Kineticist can easily do a lot of burning and blowing things up. It's worth noting though that Pyrokineticist doesn't have daily limits on many of the abilities so you'd be doing that forever.
