I can't say anything for the 152 as I've never flown it, but im currently finishing out my Private training in the Katana and its great. Given on longer x-c's the seats can get a little hard, it's a great airplane. It handles great, has electric trim, has a stick, and has gotten me hooked on low wings. It's a smooth transition to flying, and nothing beats the visibility in the canopy. I would definitely recommend the katana as a private trainer for sure.
