A couple friends have an One X. Kinda meh tbh, not many exclusive games for the xbone. One system was dead on arrival and the other is as loud as the tv. I'd wait until next gen at this point.
I had a disc drive issue with the original XBox, and then of course red ring of death on the 360. However, I've had an original XB1, an S, and now an X, and never had an issue... Maybe it had something to do specifically with the production run for the bundle? Eh to each their own I guess. Personally the PS4 exclusives for the most part don't appeal to me (I had one for a while, sold it) and the X1X has the best version of virtually every multiplat game plus enhanced versions of re-released games from last gen for free.
Right now I run an X1X, Switch, and PC combo and I'm swamped with amazing games.
