Which PPF brands are actually available and fitted properly here?

I’ve been trying to figure out which paint protection film brands are genuinely available in the UAE market and which ones are just hyped up online but impossible to find a decent installer for, because I keep reading about XPEL, SunTek, STEK, and Llumar, but when I call around to different detailers, half of them only stock one or two of these and they always try to convince me that their brand is the best anyway. I’m looking for something with genuine aliphatic TPU that won’t yellow after a couple of summers, a good self-healing topcoat, and a hydrophobic layer to make cleaning easier because the dust here is relentless. I’ve read about the differences between the leading films and it seems like XPEL Ultimate Plus is the gold standard that everyone compares themselves to, but I’ve also seen some really impressive claims from STEK about their DYNOshield being self-healing and having an integrated hydrophobic layer, while SunTek Reaction seems to offer similar features at a slightly lower price point. I found a listing that covered the Leading paint protection film brands sold and fitted in the UAE, which gave me a sense of what’s actually out there, but I’d rather hear from people who’ve actually had these films installed and can tell me whether the real-world performance matches the marketing claims. Has anyone here had XPEL installed and found it to be worth the premium, or gone with STEK and been happy with the results? I’m particularly keen to know how these films handle the combination of intense UV, sand, and the occasional off-road adventure, and whether any of them have started to show signs of aging after a few years. Any honest feedback from people who’ve been through this would be massively helpful because I don’t want to pick a brand based on marketing alone and then regret it later.
