I purchased both matte and gloss from both Slickwraps and Extremeskins... Unfortunately, I didn't take pics of all of them along the way, I probably should have.
Slickwraps Gloss - I didn't like it at all. Too slippery and just didn't dry right or look good.
Slickwraps Matte - Excellent fit and cut, just enough texture to add grippyness. Only reason I took it off was because without the apple cutout you couldn't see the apple logo at all. (Not a big deal, but since Extremeskins has it that way I wanted to try that.)
Extremeskins Gloss - same as Slickwraps.. just very slippery and didn't dry right. I'd rather go with a tempered glass back but couldn't find any that went all the way around the camera.
Extremeskins Matte - Thats what I have on now, for now.. The cutout around the camera isn't as good as the Slickwraps was, but it does have the Apple logo cutout. I just put it on last night so its not fully dry yet, assuming it dries as well as the slickwraps matte did I'll end up keeping this one on for a while.
The pics are of the Extremeskins Matte w/ cutout. I used a wet application for all, both Slickwraps and Extremeskins sent their version of the solution with the skins.
