I have the V1 3.821 and Bel 995 4.5.
I am coming to the conclusion that the V1 is better on the highway (too many falses in town, even with the X band off), I heard even 3.826 may have some issues. I find the 'J-out' feature a work-around by VR to try to justify a lack of filtering from other RD LO's.
The Bel falses much less and I do not see the constant firmware upgrades. I even leave the POP on, it works fine.
The most important spec is not if the RD can alert a little more in distance, but rather falsing. I never want to get used to hearing my RD all the time, and then miss a real threat. To me, a quiet RD is a more effective RD. You hear it, you take it seriously.
So for me, two different usage models: highway/V1, city/Bel 995. I will use both.
