I'd go for the Nikons at this moment. But really there is almost no difference in quality. Nikon may have a longer range capability B/C they really upped ranging distances last year.
I had the Leica Geos...and sold them. Great bino...but heavy. I prefer having a separate RF. Sometimes on a stalk I just carry the rf.
Plus its less to go wrong...I dunno what the warranty is on those you mentioned...but Leica is lifetime on binos...but the Geos are only 5 years for the RF. Worth considering, IMO as if you own these for a long time-stuff happens. I've had to send 4 binos in over the years [inc the leicas that leaked on my first hunt] I just sent in my 24yr old Swaro SLCs ...swaro completely replaced them with a brand new bino
Yeah, I see what you mean about Nikons being better.
GLASS-> NIKON- ED Vortex-"HD" (ED means Extra-low Dispersion, a true optical term. HD means "good glass" but not ED.)
RANGING DISTANCE-> NIKON-1,900 yards Vortex- 1,000 yards
