Drew,
If you look up and to the left you’ll clearly see ATPs logo. This is ATPs forum and all the mentors and many of the current students and instructors have or are attending ATP. Does this mean we’re salesmen? Absolutely not but it does mean that after doing our research we concluded ATP was the way to go. That aside Chris (United Airbus Capt and mentor) put together this list of prospective questions while searching for a flight school: https://airlinepilot.life/t/questions-for-any-prospective-flight-school/117/14
Give that a look, check the FAQ section and do some searching as there are many threads comparing the options.
