So I just went through a very intensive evaluation process to figure this out as well. Here is a brief background, summary, and conclusions:
I was using a set of Vortex Razor 10x42 binos and a G7 BR2 rangefinder. Really didn't like the bulk and wanted to upgrade glass and consolidate equipment. Based on my use of the G7, I wasn't willing to sacrifice ballistic solutions w this "upgrade".
I evaluated the the Sig BDX, Vortex Fury w AB, Zeiss Victory RF, Swaro EL Range w tracking assistance, Leica 3200.com.
Sig BDX — got the party started with incorporating AB (ballistics) in binos. Onboard ballistics solutions to 800 yards or connect to kestrel via BT for unlimited solutions. Surprisingly good glass for the price point.
Vortex Fury w AB — New for 2021. Best Ballistics solutions of all rangefinding binos evaluated. (onboard, connect via kestrel, wind inputs, etc). Also by far the worst glass.
Zeiss Victory RF — same price point as Swaro, weak ballistics program and no ability to input wind. You'd have to really be a Zeiss fan to go this route IMO. I'd look for them to be the next to upgrade their rangefinding Bino.
Swaro El w tracking assistant (New for 2021)— Best overall glass (but still has that slight tint all rangefinding binos have). Weak ballistics program. Again, no wind. The tracking feature, which could also help stalk a bedded animal, is cool but not not enuff to overcome the weak ballistics IMO. I was hopeful Swaro would get this right but they missed the mark IMO.
Leica Geovid 3200.com. Glass might be slightly below Swaro and on par w Zeiss. Still premium glass. Onboard ballistics app is weak and I wouldn't trust it beyond 500-600 yards. However, this is the only alpha glass option that links w kestrel. Admittedly, I was skeptical as there was a lot of negative press on the BT connection when they first launched. That being said, Leica updated the firmware and following a couple weeks of testing, my unit works flawlessly and is actually gives wind readings faster than my G7 (manually inputting wind).
I purchased the Leicas and look forward to using them for many years to come. If you decide to go with one of the big 3 (Swaro, zeiss, Leica), don't be afraid to be negotiate. They are required to list MSRP but every single store I visited (not big box) or called was willing to negotiate on price ( this wasn't true for vortex or sig).
I could go into a lot more depth but this should get you started. Best thing you could do is download all the apps to see the functionality and then go look through them at a local retailer.
