Q2 Is way better for quest-native games ( much better SOC ), and the Wifi6 enables a higher bitrate 100mbps -> 150mbps for PCVR streaming. It also has fancy ASW which can be nice if you are able to tolerate the ghosting artifacts. 
Otherwise it's mostly a screen side-grade: 
Q1: OLED but caps out at 72hz
Q2: LCD but can go all the way to 120hz.
