Being a bit lanky, I fly the PA-28 out of necessity, purely for the extra room. My club has both, 1x C152 but 11x PA28 so bit of flexibility as well incase one goes tits up.
I enjoy flying it , no reference point to compare the C152 though. Don't think it would be a detriment to your training to change aircraft. mix it up a bit!
all the best with it.
