The Passport 9500IX is by far the best detector I've ever used. While you think you don't care about falses, you'll be sorry down the road (pun intended). The GPS learning function is worth 10x its weight in gold. As for sheer detection, I think the tests put it just a hair behind the V1 but we're talking extreme distances to begin with (ie, it doesn't matter if one detector picks up a signal at 2.2mi and the other at 2.0mi...you're still notified well in advance). The V1 is old technology, you'll get false readings that will make you pull your hair out and ignore the detector completely, and you're still paying $500 for it. Would you buy a 1st gen iPhone for $500 now that the 4th gen is out and priced the same? Me neither.
As stated above, these are radar/laser detectors, not cop detectors. If a cop is sitting with his radar off and then pegs you as you go by, it doesn't matter if you own ALL the radar detectors on the market. Radar jammers are illegal and laser jammers are available in many states if you want more protection. I still wouldn't use them as a crutch for faster speeds though...I'd consider them to be a bigger insurance policy to avoid tickets while driving the same way I do with a detector alone.
I'm not going to get into how to maximize the effectiveness of a radar detector on here as I'm not condoning anyone drive around at illegal speeds
