I like Pipers slightly better, probably because I have much more time flying in them then Cessna's. Cessna's also seem kinda cheap to me, while on the ground, they move and twist much more in the wind or even if you just push a little on the wing. Plus the landing gear on Pipers seem much more beefy. I used to instruct in a nice 2001ish 172 which I thought was great...had a lot of power, quiet inside, and with lots of room. The 150 I think is a death trap, being stuck in a sardine can and the power is completely inadequate-wouldn't be bad if your flying alone with half tanks, but with two and full tanks at max gross, takeoff and climb performance is scary.
