htc or index if you want to use fbt and have enjoy having proper tracking of your hands/headset at all times. Not to mention the ease of just opening steam vr and playing your games.
Oculus Quest 2 if you don't give a shit about facebook tracking your activity and selling your information. The headset seems amazing for 300$ but the you realize you need to spend another 200$ to make it comfortable enough to really use for extended period of times. I guess if you plan to play standalone quest is also a bonus or if you're someone without a decent rig.
WMR if you can get one in good shape for 150$ or so isn't bad. Samsung especially was decent when i had it. Good budget option if you don't want to do lighthouse tracking but hate facebook.

I spent like 260$ on a used vive in new condition and another 330$ on trackers and straps and love it. Eventually i'll get knuckles/index or the full index kit if i feel like it. Might just hold out for a while and wait for whatever htc/valve drops next.
