So i was in the exact same situation as you a year ago. I was seriously considering ATP. But, I ended up just staying at my local small school. My thoughts over the past year

Small school:
Pros

-I saved about $15,000
-guaranteed CFI job (with medical and dental benefits)
-small school vibe, they actually seem to care about my progression

Negatives:
-slow. What I could have done in 6-7 months at ATP took me a year
-Our fleet isn’t as big as our demand for airplanes. So when an airplane goes into maintenance it messes up a lot of bookings

so I don’t really know. Sometimes I wish I did ATP because I would have finished a lot sooner. But at the same time, my school has some students who had previously been at ATP and most have horror stories
