Everybody has there own opinion, mine is the safety of my students. I have no quams myself flying the 152 infact I did all my ratings in one and have spent about 600hrs in it. To this date I have been and instuctor for two years and have a good pass rate. I have given over 450 hrs of instruction and have determined that the 172 makes for a safer environment for my students. Better equipment, performance, more room, quicker times to get the private. Now that was the answer to the original post ok. I think the mighty 152 is great plane in it's own rank, it's more fun, cheaper, and a little more forgiving on those hard nose wheel landings. There both planes are equal no one wins.
