I don't have a favorite but the last few years I've used a 10x42 Leica Ultravid HD that I like a lot.
Ditto an 8x30 Swaro SLC.
When I had it available to me,I frequently put everything else down and grabbed a 15x56 Swaro SLC for distant searching or to pick apart deer,elk,and antelope for trophy quality.....awesome. I should break down one of these days and buy a set.
