When I was learning to fly I started on the 152 but moved on to the PA28 as I found it a roomier and more comfortable environment to train in (I'm 6'2" with long legs).
I find the PA28 better in turbulence and nicer to fly on cross country flights than the 152. It's also a more stable IFR platform.
I prefer the handling of the PA28. It's also IMHO more forgiving at the stall.
After seeing what a 152 can do in a steep turn at the stall (demo by an instructor) I'll stick to the PA28
