While I don't have any experience with the bow rangefinders, I looked at rangefinders extensively before picking my Leopold. I chose the RX-1200 with illuminated retical. I compared it to the Vortex Razor. (And others at cabelas).
One thing that I noticed about Vortex. I was ranging a mount on the far wall and the range fingers were all at 41-42 yards. But the Vortex Razor was at like 45 yds! A +/- of 4 yds!
I was worried about going to extender ranges and being off by 10-30 yds off out to 500-600 yds. Kinda disappointing because I love all my Vortex optics. All my scopes are Vortex FFPs and I have a set of 10x42 Gen 1 Razors as my backup binos, so I really like their products. But I also think Leupold (while more expensive ARE brighter, but also more expensive.)
So I went with the Leupold. I figured if I didn't have the right range, nothing else mattered.
