I'm in the same boat as well. Probably the most discussed comparison. But never any solid conclusion is reached.
Apparently (from what Ive read)the V1 can detect radar at longer ranges than the 9500. It can also detect QuickTrigger a LOT better than the 9500 (a lot of cops use this method).
The 9500 on the other hand has built in GPS, so it eliminates false alerts and stores them. It has voice. And is blue! It cant detect quick trigger as well as the v1 (most of the time it doesnt even detect it), and detects not as far as the v1.
Both units dont have laser protection, but I think they both have laser detection. So if you hear that going off a lot, time to invest in a laser jammer (if its legal in your state).
All in all, V1=better detection, longer range, but more false alerts and older looking
9500: good detection, not as great as the v1, cant detect QT as well, less false alerts, newer looking, voice.
V1=better detection
9500=Ease of Use, Convenience
That sound about right?
