If you want to get it done quick with twin time, a guaranteed price, and within a defined time frame... then ATP.
If you are more flexible in the time frame, don't need or desire the twin time, and don't mind being flexible with your pay structure... then like DE says... check out the smaller schools.
Either way... keep your options open, visit the schools, ask the same questions across the board to each one of them so you have a firm base of information to compare them all to.
Asking in one forum which school is better will definately get you jilted results. Instead... like you have already partly done... you should list your situation, experience, and goals along with specific questions relating to flight training. That will keep the "Flight School Wars" down.
Everyone has an opinion and most times we all think ours is best. You'll see that come up quite often, (as you already have in here). What matters most though... is YOUR opinion.
The more you know...
