Any NROTC unit will provide you the opportunity to earn a commission. Picking a school based on the perceived reputation of its current NROTC program might seem like a good idea, but as with everything else, luck and timing will come into play. A new MOI or AMOI can come in and turn a 'bad' program 'good' or a 'good' program 'bad' in no time. What seems like the perfect program now might be a clownshow by this time next year and vice versa. If you want to pick a school because it has a certain academic program with a good reputation, that's different. That's built up over years or decades and typically won't change overnight.
I know in the end you're going to do what you think is right, just be aware of how quickly and drastically a unit can change.
