well, im quite anal on this screen protector thing, cause i realy want it to be perfect. and i don't like those matte ones cause it still shows fingerprint and dirts and it make my iphone screen look like a CRT monitor, so grainy. so far i've tried theese and here's my thought:
-SGP ultra crystal - cuttings is perfect, but the screen protector it self is not so crystal clear, you can see some "grain" on them , i suspect is their glue that make it look like that. another thing is that their glue is not so good cause it always lifting up in the corner. i give them score of 6/10
-SGP Oleophobic - very good in the first week also, cutting is perfect, but it loses its oleophobic after a bout a week, and then it become the same as the ultra crystal, but this one is more prone to scratches. score 6.5/10
-SGP ultra fine - this is matte type and i don't like it at all score 4/10 for their perfect cutting.
-Power Support AFP Crystal - perfect cut, very crystal clear, mind you but i buy the japanese version which clearly write "AFP" anti fnger print on the packaaging but it still does shows finger print like any other crystal screen protector out there. but this is the best in teerms of crystal quality. it's sooo damn clearr. and its easier to apply than SGP one, cause SGP one are using sometipe of glue that shows some specks or blemishes if you don't put them perfectly. score 9/10
-Martin Fields - the best cuts out there, excellent claritttty, but it does shows a little bit of the rainbow effect. their protector is the thickest of them all, so it may cause problems with some case. but it does "protect" the screen more because of that. score 9/10
now im using martin fields for my back cover and power support for my front screen, great combo i must say.
