Hard to answer such a subjective question. At one point in my optics arsenal I had a pair of Nikon Monarch 5 and they were awesome. My
Uncle still uses and loves them.
I’ve made my way up to EL’s now and much prefer them. Absolutely a worth while upgrade for me but I spend a lot more time behind glass now than when I used Nikon’s.
They were a great quick look optic for me. Something to grab or freehand glass for short terms while I was on the move. I didn’t find them as nice as others once i started spending hours behind a tripod and really picking animals a part vs just filling the freezer.
I tried a few, some better, some worse and settled on the Swaro EL’s because I found them the best for my uses. I really wanted to like the SLCs and the Nikon HG’s with the field flatteners but they didn’t work as well for me.
Razor HD’s were a nice upgrade from my Monarchs. They had a better view to my eye, they were more comfortable on my eyes and felt better in my hand. I think they were lighter.
So many factors to your question - are you looking for a better warranty, improved clarity, materials, FOV??
I always considered The Nikon Monarchs as a great, serviceable and underrated bino in its price point. Good bang for the buck in all categories.
