A few thoughts:
141 vs 61 - doesn't matter, you will have the same PPL at the end of the day. And it doesn't sound like you're positioned to get any of the R-ATP benefits (as you have to do your training through a University program).
141 is more structured. 61 is less structured. Which do you like? You will take the same check ride at the end of the day.
The biggest differentiator is probably how quickly you want to train. Typically, a 141 school has more airplanes and more instructors, along with AATD/Sim devices, that will allow you to progress more quickly. Your local independent 61 teacher usually has 1 airplane and when it's down for mx or the weather sucks for a week, or they go on vacation you lose that week.
