I learnt in the 152 and the Aerobat 152 and loved them.
I have flown in the Warrior and although a nice a/c I didnt like it much.
Low wing - making ground visuals a bit harder, banking left and right does solve but a bit annoying , especially with in circuits where as the 152 has great visibility.
Although smaller the 152 handles very well and is not a mjor issue unless you are a fatty.
Also very much disliked the tank switching every half hour to stay in balance.
Also had an incident where the left hand strut collapsed after landing when clearing runway ...not nice.
for my 2 cents I would fly the 152 anyday.
