I had a stock and it felt amazing. Didn't bring any massive advantage to the table, but the overall feel was really to die for. It just removes this one layer of abstraction VR has where you're holding two independent objects mid-air instead of having them directly linked to each other, and I'd say it's really worth experiencing.

If you're playing some kind of pavlov, 90% of the time you're shooting someone ~20m away while running, so you don't really need all that much precision. Stock takes away some of your mobility and some dumb things you were able to do become impossible, it's also somewhere on your body all the time so it's just a bother to have it whenever you do anything that doesn't involve it (handgun, grenade). 

I'd use a stock every now and then, but I'd do it only for the feel, not for performance.
