I trained in a C-152 all the way through my PPL and loved every minute of flying it. It was (to me anyway) a very easy and straightforward aircraft to fly.
After I passed, I switched to a Piper Warrior, simply because the fling club I joined had no C-152's. I a couple of hours conversion training and now I fly it all the time.
Verdict?
Warrior easily beats the C-152.
It feels more sturdy and safe. It is wider to sit in and it has a better interior. A friend of mine, who also converted from the 152 to the Warrior, told me that it was akin to driving in a Robin reliant and then driving in a Ford Focus.
But having said all of that, I do miss the 152. After all, it got me through the PPL.
