I'm not the search police, but there are extensive discussion in the Accessories Forum: https://forums.macrumors.com/forums/108/

I did a lot of poking around there before I bought mine. Lots of good information! For me the discussions kind of boiled down to display degradation vs. fingerprints.
 
Yea the accessories page is great, I think the two most recommended companies are powersupport and sgp. You can go from there and pick matte, oleophobic etc.
