No experience with it. I honestly don't think using one film thats more expense than another is worth it. As long as it doesn't go purple, and it keeps out a fair amount of heat, I'm happy with it.
The only tint that I would spend extra money on is ceramic tint, but that costs an arm, leg, and your first born.
I went to Airpark Tint in scottsdale and was extremely pleased with their service. They didn't freehand it so the tint is ground off at the very edge of the window (no line of clear glass). Looks very nice.
