Hit the SGP site. Select each option under "Color" and click on the thumbnails and read up on each one. Also, don't overlook the countless existing threads on screen protectors.I just have no idea what the difference is between the Ultra Fine, Ultra Optics & Ultra Crystal.
Ultra Fine. Crystal picked up too many smudges and had too much glare for me. Ultra Optics causes too much distortion for me. YMMV as this is a highly subjective matter.What is your favorite?
Best is always highly subjective, regardless of topic. UC was not best IMO. Again, YMMV.If you are not using a stylus, then Ultra Crystal is the BEST out of the three.
