quest 3 is the obvious choice. for the money nothing else touches it (for the record however I don't have one, I have a quest pro)
elite in VR is a totally different beast. monitors ,.even good ones don't come close.
sadly all the on foot stuff even in VR is on a big cinema screen (but the quest 3 is good enough for that still to be ok)
but everything in ship and in the srv. elite is phenomenal.
ime for seated games it's worth getting a (good quality) usb cable and running over usb3
it's a bit better image quality than wireless
get voice attack and a voice pack for the game. it adds so much to the immersion and covers.lack of vision of your keyboard for stuff like shield cells, chaff, ecms and what not.
whilst at it if they float your boat buy dirt rally 2, pcars2, half life alyx, MSFS2020, starwars.squadrons, lone echo, hell there are loads but they will give you a taster.
