Wii only. I had always been a Nintendo fan, but after the 64 I started playing on PC and skipped the PS2-GC-XB generation altogether since nothing there seemed to me to offer what the PCs could (and to some extent most still don't). Wii brought me back into console, since it was new, fresh and a really original take on gaming that I wanted to experience. I've said this here before: most gamers are conservative as so many people are conservative, all things taken. The habit and wanting things to not change, just to "improve" a bit is a cancer to society. Motion controls had so much potential, but your regular Joe would go "nah, I prefer games with a regular controller and blah blah blah because that's what I'm used to". To some extent, this lack of wanting different things is probably a part of why there is so much difficulty in integration with differences in a society. I mean, seriously, if one is not open minded to experiment something different and try to see how much better it could go if the investment would continue in something so unimportant as videogames, what are the chances that would happen in really important points of our lives, as, for example, rights of minorities? Well, that's something of a rant, but there you have it.
As for the Wii system, it was amazing. Some of my most treasured experiences in gaming happened on that little beautiful machine, like the communities from Excitebots, GoldenEye (FPS would never be the same...) and especially Monster Hunter, but above all I could have my father, who had always hated games in general, come to my place to play bowling. I only got it 2 years after its original release tough, since the PC provided what I needed in terms of gaming, mainly through emulation.
Finally, after my early teens I would not see myself caring for handhelds anymore (had a OG Game Boy), since all of them (PSP excluded) would look toyish. Regarding recent times I have to say I loved playing WiiU on handheld mode and continue to enjoy doing so on Switch.
