I've used a few different places over the years.
Quality Window Tint: Used to be the go-to guys. But something changed in the last few years. It looks like they scaled WAY back. It's tough to get an appointment, and the work was good, but not great. I rate them a "Meh" these days.
A2Z: Friendly guys, and they do a good job. My only issues is that one of the guys was wearing a big gold chain bracelet while he worked on my car. There were no obvious scratches, but it should be common sense to remove all loose jewelry when working around a car.
Automotive Appearance Pros: Good guys, they've never disappointed me when it came to vinyl work. Tough hours to work around however. My only complaint was that I let them talk me down from ceramic tint to dyed film and I completely regretted it afterwards. But that was my choice not to stick to my decision. (BTW, get the good ceramic tint, it's worth the extra $$)
Performance Auto Spa: Just had them do my latest car. Good work, I'm very happy with the result. They're the only shop where I didn't wait around for the car, so I can't comment on their practices. But not only did they tint the car, they gave it a quick detail too!
Right now if I had to tint another car, I'd take it to Performance.
