I am assuming that you are referring to the 3rd generation Razor, which is a much better bino than the earlier versions that can still be easily found. We have an 8x32 Conquest HD, and a 10x42 Razor 3rd gen.. When I was shopping for a good 10x42, I tried the Conquest HD, Razor, and Meopta HD. I finally decided that there wasn't anything about the image from any of them that would make me pick one over the other. All three are excellent! However, it was my subjective evaluation of things such as focus knob feel, texture of rubber, overall appearance, overall handling, etc. that made me prefer the Razor over the others.
I will say that at current common retail prices, the Razor is not what I would have ended up with. I do not believe that it is worth more than the other two models, but should instead be priced about the same. Because of the price difference, I was about to go with a Conquest HD. However, I came into a used but essentially mint condition Razor at an excellent price, so I jumped on it.
I wouldn't worry about picking either one as far as the view is concerned. Instead, make your decision based on your wife's subjective evaluation of things such as ergonomics. Keep in mind that these have a fair amount of weight to them. Does your wife already have experience with moderately-heavy binos, and is willing to deal with the weight? I ask because my wife does not care for our 42mm binos, even if the Razor is one of the lighter ones. If your wife is already used to the weight of these 42mm binos, then you won't go wrong with any of these three.
