It's definitely worth it for me, but that's mainly because I lucked out in getting the Game Pass covered until April for just a buck, since I had already bought a prepaid XBL for the year in January I think.
Also helps that there are a ton of games on it I want to play - Horizon 4, Rocket League, Hollow Knight, Tomb Raider, Just Cause 4, Borderlands 2, early Gears 5 access, etc.
