I am one of the few think the TNG style uniform is perfect. I have never liked the gray version. I never really warmed up to the DS9 version either and wish they'd used the TNG one.
I suppose it'll be interesting, when we reach TNG season 7, to see how the uniforms/sets look in HD. That'll tell us if that whole "too worn down" thing is an excuse. Which I don't really buy since they redid the bridge to begin with.
