I agree with Ron and Orion, BUT if you don't plan on sitting behind the glass and really using them then money is better spent on other gear, but if you don't have good glass then you'll probably never spend that much time behind them anyway because it's annoying. I use cheaper glass because I don't have the patience to glass and have good eyes, spotted two moose there other day while making a sandwich at over half a mile away, used my vortex diamondbacks and confirmed it was an animal because it moved, had they been bull moose I would of known they were moose. So it all depends on what you want to do. I got by for years with just a 10x monocular. To your particular brand question, I think the price difference is worth it if it's within your price point for the two you mentioned! Nikon has great glass for the price as compared to other brands!
