If height/weight is not a concern go for the C150.
Yes its ugly and slow but its a great trainer as it shows you all the important bits at a leasurely pace:
Yaw, roll, adverse yaw,right turning tendencies, stall buffet..acceleration or lack thereof..all great stuff.
The Pa28 is like an American pick up truck, waaay less feedback through the yoke and I think the C150 is better for teaching landings.
You can do beautiful crosswind landings on one wheel, try that in a Piper dumptruck.
* If it matters I have 8000hrs of instruction given, probably a 1000 in the C150/C152 *
