As I said in my previous comment on the thread, I am currently using the matte option from WorthWrap, they have a hydrogel clear as well. I have a curved screen device as well but it's pretty good for like 3-4 months. The best option though, remains to be the one you can get locally with a physical inspection. I know of no premium brands selling the stuff online.
As for flat screens, Ringke has never failed me with quality tempered glasses.
