I'll add to these

1. Software doesn't break by user action or other installed apps, no viruses etc, no slowdown with time, no OS reinstall needed
2. No launcher for games, overall start time is much quicker
3. Cloud save for all games on Xbox, you change the console and all your progress is with your account
4. Mental separation between fun on console and work on PC
5. No fiddling with game options to find the best detail level for the hardware
6. Be a part of home/family life in the living room, instead of being hidden away in a home office separate room.
7. No need to chase hardware upgrades as time passes and games become more demanding
8. No need for fiddling to run old games, if they are supported then they just work. Also no risk of losing games due to system/software changes after 5-10 years.

Some of these are from my experience. I was playing on computers (not only PC) for 30 years and then switched to consoles just a few years ago, that was life changing for me.
