SunTek is Eastmans garden variety line of window film. Eastman who also owns Llumar and the Pinacle line..likes to promote the Pinicle line as one of their premium brands. ..Does it mean the film is better? ...maybe maybe not..in most cases any difference between them will be negligible at best. What is more important to the end user....( you ) ..is the quality of the job the guy sticking it to your windows does. As I said in my first post. Visit both shops and look at their work for yourself. Just because a tint shop hangs a luxury brand shingle on their building, does not mean they have quality installers inside. In many cases.. they won't.
