It sounds dumb but my pick would be the SNES. There’s just something about 16 bit games I love.
The SNES has so many good games, like sf2. The first party games and some good arcade ports.
It also has a lot of good RPGs, like chrono trigger
The controller is really cute
Tho, the PSP is a close second. Tekken dr running at 3x resolution looks beautiful
Yes I’m a sucker for dpad centric devices. Yes i love emulation.
16 bit stuff looks amazing
The challenge with this question is that not everyone has played in every console, so like, for me, I can only comment on the Atari 2600, the Wii and the XBOX 360.
From that small sample, the wii wins hands down. I loved the motion controllers a lot.
Never played Wii but it always looked cool to me :3
I think because it was so different from what came right before it: Gamecube, PS3, Xbox.
Waving that Wiimote around was a blast for everyone, gamers and non-gamers alike. Tons of hours of play in this Sports Resort, for instance.

I get what @berttheduck said about long games / serious gamers but can you imagine your grandma trying to play most Switch or PS5 or other new console games now?
