Thank you @highplains for the response! I ended up going with the shop that had good ratings and that a friend had also used. Not to mention the hot tint installer girl haha.
Turns out they used MaxPro on mine (but they use others too).
After alllll of my research, I agree that the "difference" in brand probably isn't so much felt by the consumer as it is by the installer. It's probably most important that an installer is using something that works for him or her (in regard to the product itself, warranty, cost, etc.)
I could be wrong, but it seems to make sense. Also, a hot girl installer with a foreign accent....... definitely helps haha.
edit: I was also sold because they said they had a display and almost any % I wanted...... I went to see the display and was sold by the % I wanted by the hot girl.
MaxPro was kind of left over from a % they stopped ordering but that I wanted (the guy said they didn't have it...then he ended up on a call, so the girl took over and found it).
$260 for a 4 door sedan
You guys rock! Thanks! Hope this helps installer "dudes" and "dudettes"!
