Hi there,
Based on my experience, I would recomend the C172.To me it is the best A/C for training (Safety,handling and the yoke). In C172 I have felt a real aviate,while in the DA,I felt like flying a simulator..
Anyways, try to get more information about the two schools as a matter of quality and relaibility,,,oh do not forget the wx issue (you may spend many days waiting for a good wx just to have one flying hour)...
Good luck
