Some Burris are low-cost (i.e., "cheap"); some are not. No different than any other optic line. As pointed out there is a difference between a $200 Vortex and the Razor. There is a difference between the Leupold MkIV at $1,200 and the Mk6 at $2,000. The Burris RT6, the XTRII/III are 'as good' as any other optic. The other LVPO that is getting more love is the SWFA 1-6. Not cheap but also 'as good' as any other in that pricepoint. What you are looking for in 'durability' is normal use/normal wear and tear based on your use. I wouldn't call that hard use.
