Worry more about the instruction than the aircraft. By the time I completed my PPL I had time in PA38s (35 hours), a PA-28 (10 hours) and a super-decathlon (40 mins). Since then I have flown mostly 152s, and swapping to them wasn't a problem.
C152s are a bit small, but other than that it's much of a muchness. There are some things that they teach well - I think you need better rudder co-ordination than with the pipers - but stalls are disappointingly uneventful compared to a PA-38.
