The difference in image quality between the pts and the comparable pulsar is a wash. So it would come down to users preference in operating system, and customer svc/support in the event breakage/malfunctions. In my personal experience, I prefer pulsar operating system, and customer svc. I own and use all three of the major mfg. I’ve also needed warranty on all 3 . pulsar/Sellmark is the best to deal with in the event of failure. Armasight was the only mfg I received a non functioning unit right out of the box. This was recently, after they were absorbed by flir. But in fairness, I can’t say what, if anything flir has to do with flagship armasight stuff. Maybe it was sitting in the warehouse for a year before the buyout..... I should also note that my trouble with support was with IRD, before they were bought by trijicon. I actually had a trijicon rep contact me and get situation resolved, as the buyout was in progress. I’ve only purchased one unit directly from trijicon since then. Have no issues since . Hope this helps
