ATP seems to be a decent program, if you can properly prepare, and handle the super-sonic pace. WestWind is a decent and reputable school. Their training is top notch. Both have their ups and downs; based on your luck of the draw with instructors.
Make sure you prepare yourself for with a 4 year degree before entering an accellerated flight training center. Several schools advertise an afilliation with degree programs (UNLV, UVSC, etc...) make sure you have time to take the online classes.
I have personal experiences with both schools. PM for details.
