Yes and no. I was with European Flight Training (JAA!), they are sharing the facilities with Aviator - and helping each other. Two of my roommates were with Aviator and they were quite happy. Following my stay another Belgian pilot I know but with a FAA CPL eventually went to Aviator for his ME and CFI training as well - no complaints. BUT remember, nothing is perfect here and like everything and everybody there are pros and cons.
If anything I would say they weather in Florida is quite variable, so you have to pick the right time of the year.
