Glass is too subjective to be "best". What my eye/brain says is super best is not what another eye/brain sees. Plus in my opinion, yes opinion, name brand gets extra points depending on who you ask. We did an outside optics demo with most top shelf brands, had them covered and masked up as best we could. Had customers come up and take a peek through, answer some questions. It was funny to see high majority percentage of customers say Swaro is top shelf to pick another brand as their best. Scientific and prove the point, no just a demo but the results were interesting.
Trijicon to me has super glass both in clarity, low light, true color, the whole gamut. USO is top shelf to my eye and I believe they both use the same glass, Schott.
Exactly what you are after?
How much extra time do you think a $3000 scope gives you Vs a $500 or how much extra time do you want/need?
From my experience, Leupold offers some of the industry lightest and smallest scopes for a comparable scope. The reason I prefer them topped on my hunting rigs.
FFP in my book not needed for hunting as neither is a milling ret but I hunt to fill the freeze not make it a sporting event at how long I can shoot, I prefer to use hunting skills not shooting skills.
good luck
