My PC isn't very high-end or anything but it's typically where I like to do most of my gaming. Whether it's directly on my PC through a mouse and keyboard, or through Steam or emulation and using a controller, I've found it to become more and more comfy as time goes on. I guess I just like having everything on my desk.
I'll go back to my Switch every so often if I'm either away from home or there's something specific I want to really commit to, then I'll dock it and play it on the TV during the day, and lay in bed with it at night. Nintendo handhelds have always been comfortable to me, they're what I grew up on. Stuff like the DS and 3DS are ones I'd only pick up if I'm playing a game I physically own, but would have no trouble enjoying playing on them.
This year I've been using our Xbox One more often, and while I usually don't enjoy sitting on a couch in front of a TV for hours and hours like I would PC gaming, I think it worked somewhat well for me.
