Neither. Get a non aviation related degree, go to an fbo or mom and pop flight school. Dont be fooled by the marketing if ERAU, UND or or "aviation colleges". Same goes for ATP, skip it and save your money but ATP certainly isnt as expensive (but is only flight trainign.). If i could do it all over again, id go to UW Madison, engineering and do my flight training at the local airport.
I went to the local airport (msn) and it was great! But got a degree in aernautics through ERAU online. Actually it wasnt too expensive comoared to UW, but its the degree i regret. Its not useful outside of aviation, and only helps gets u into an interview but isnt a deal breaker except at the majors. How you get along with the people, who you know and your flight time is most important.
Lets talk numbers- ERAU degree and training 250k, UW wi and training and local airport, close to 100k.
If you think thats worth the 500 hours of flight it shaves off your "atp" requirements just to go make 20k a year at a regional then you need to rethink being a pilot. You live and die off smart decisions.
Im serious, you will regret it if you got to ERAU or similar.
