Depends how you look at it, if I had the money I would choose the DA40 anyday over the C152.
Anyhow, why didn't you compare another 2-place aircraft like the DA20? I have flown both a DA20 and C172, where I'm from the altitude is so high that very few people do training in a 152. The DA20 is pretty sweet, electric trim, control sticks instead of a yoke, and its handling characteristics are really nice. Plus i love the pull over canopy-style door and hte great view it gives. The 152 is a time tested trainer and is completely adequate for flight training, but there's something really cool about flying in a diamond aircraft that I can't explain.
