Do you prefer Commodore or Falcon? Both C150 & PA28 have idiosyncrasies. The Warrior is a more useful aircraft for taking passengers and flies a bit faster. I think I'd vote for the C152 as the better training aircraft, but the real deciding issue might be a) which type the school has more of (which will mean you'll have less trouble with aircraft availability) and which of the aircraft are in nicer condition. It wouldn't hurt you to ask to sit in each. Use the time to gain a bit of familiarity with where all the knobs & buttons are and see if there is one that you just feel more comfortable in. I disagree with the bit about sticking to one aircraft type. My view is that if you want to learn to fly rather than operate an aircraft, then more types allows you to understand the art and science of flying better.
