I'd go where I knew I wasn't going to get smoke blown up my hole, where there was quality over quantity, pukka sparring, excellent training & fight knowledge from the trainer/s, and where you'd have decent team mates
I'd probably have multiple gyms to get the best quality training and sparring ,as my home and main gym I would have a smaller 1 so I get the attention I need from my head coach who I need to trust in fights to put my safety and interests 1st and also maybe even helping decide when it's time to retire which seems so hard for so many in MMA and boxing. You see it so often some of these fighters are to tough for there own good and don't know when to stop, a good coach tells you what you need to here not what you want to here.
