My initial impression of the 172 vs. the 152 was one of sitting up, instead of laying down. So far as a light economical, straight forward light four seater, the 172 is an outsanding airplane. It's strong, simple mechanically, and is a great design.
I've instructed in them, towed banners with them, flown freight with them, and operated them from dirt and gravel strips as much as paved ones in all kinds of climates and terrain and weather, and still think it's a great little airplane.
Moving from a 152 to a 172 is a very natural step; you'll have no problem at all.
