I must say I don't remember it looking that amazing at the time. It was clearly a little bit better than the PS1 for graphics, but the 4k of memory for storing texture maps was a big shortfall that made things look rather plain and smeared in vaseline.
But, even with a PC and 3DFX, I did envy stuff like Goldeneye, Wave Race and Mario 64.
I've got the N64 controller for the Switch. I got it out of curiosity. I can see why it's ok for stuff designed for it, but for general Switch stuff, don't bother as, as well as the odd layout, it's missing loads of buttons like X and Y, rendering games you can't remap useless.
