Starting with your questions:
> Do you enjoy gaming on an iPad?
Generally no, unless I'm playing a game for which a touch screen provides a good interface. Board/card games are great. "God view" games can be done well. Most first or third person games of any variety suck.
> Are you a Switch person?
Not really. The Switch is too large and fragile to be pocketed so it's only really portable in the sense that it's not tied to a TV, which means mine just lives in its dock 95% of the time. As a docked console it wasn't even competitive against last-gen hardware, and as a result it exists solely because enough Nintendo first-party games came out that I wanted to play.
I was a huge DS person in its era, because I could have it in my pocket anywhere. Pull it out, open it up for even half a level of New Super Mario, then slap it shut and it's immediately suspended for later. Switch has the same function but without the pocketability it's just not as useful.
> Or do you have a dedicated gaming PC at home?
Always have, always will. The PC is the longest lasting gaming platform on its own, rarely has it ever lost the performance crown, and thanks to both inherent compatibility and emulation it can play the majority of games ever made for any platform.
I have consoles for convenience and exclusives, but a good PC is a long term investment that pays off if you really like gaming.
