I saved about £400 by training in the C150, then did a 2 hr check flight, to upgrade to the Warrior. When you've got the PPL, the Warrior is the far better aircraft to build hours in, as it has a far greater range and speed. If I had to re-do my PPl, I'd be happy to do it in the C150 again, although the warrior feels more like 'big real' aircraft. It seems odd, that you say there is a negligable cost difference between the aircraft.
P.S. Don't try steep, slow C150 approaches in a Warrior (unless your aim is to entertain all spectators with your multiple landings (A320 crew at SFD, FL, in my case)).
