I have several high end riflescopes, and try not to join fan boy clubs, but if I was going to, it would be Swaro. I started off with a 10x42 SLC and an STS-80HD. Both were fantastic!
I will say there are other brands I like, and like a lot. I have a Leica 10x42 UVHD+, and like it so much I've considered selling my STR-80 and buying a Televid APO 82. But I also have 2 Swaro binos that have kept me grounded.
Granted, I've never had any other high end spotters besides Swaro, and never even had a chance to look thru any in the real world. I know I'm not missing out on anything with my STR-80, though.
If you have the chance, get behind as many high end spotters as you can. Swaro, Kowa, Leica, Meopta, all make some great glass, albeit a little different. You'll likely find something about 1 that you like better over the others.
