I'll play a different angle/take on this thread.
Anything from Vortex. Let me explain.
Last year, I dropped my gun while trying to get it out of my pack sling and it landed right on the Viper scope. I could hear glass was broke. Returned home and called Vortex about how to go about returning the scope for their lifetime warranty. Phone rings, a real person immediately answers. Most helpful person. Scope replaced and back on my gun in about 3 weeks time.
This year, not sure how it happened during travel but I get to my hunting spot and when I started to glass, I noticed my adjustable eyepiece was broke on my bino. By the end of the trip, it was completely broke off. Same drill - get home and call Vortex to setup the warranty replacement. Not only did a real person answer but once he got my address and saw where I was from, he started talking waterfowl hunting with me in the area.
So, in conclusion Vortex has top notch customer service and I will never have to buy an optic again in my life unless I just want to own more of something. I now own 3 rifle scopes, 2 binoculars, 1 spotting scope and 1 rangefinder. Are they the best optics on the planet? No. Are they American made? No. Are they the best value on the market? YES!!!
