Radar questions

Reason behind this is that a guy wants to trade my old stereo stuff (jbl 1000:1 amp, 2 audio bahn flame q 12’sm and 2 old atomic thunders) for a radar, but he works at best buy and the best they can do is the passport no V1…so if anyone knows if i’d be better off with the 8500 x50 blue over the 9500i lemme know!
