FlightSafety is considered one of the best aviation training organizations in the world, not just in Florida. The Vero Beach location has provided the highest levels of professional flight training for 50 years.
Of course reputation is only one factor in selecting a flight school. Cost, location, student life, personal fit/preferences, etc., are all important. Some FlightSafety students dub Vero Beach "zero beach"... not exactly the party place, but maybe that's a good thing if you actually want to study!
Another option, if you're at all interested in getting a full 4-year aviation/aeronautics degree (not just flight training) is to apply to Embry-Riddle Aeronautical University. They are also globally recognized, and they have a campus in Daytona Beach, FL. As a degree student you would be eligible for an F-1 for the duration of your degree plus the 1 year OPT afterwards.
