Stocks are generally a waste of money. The anons here who got one or made one gave up on using them since it makes it a pain to do stuff like throw grenades. It's up to you though I guess.
Either a wheel or a HOTAS might be worth getting if you've got any interest in sims.

If you're willing to wait for reviews, the G2 could potentially be better. I'm not sure I'd trust WMR tracking over Oculus though.
