Beat me to it
Never tried the Dreamcast one, but the Saturn Twin Stick is one of my prized possessions. As is the smattering of Virtual-On merch that I have peppered around the house.
(not my photo - mine's a little more beat-up and well-used than this one)
Fun Story: My wife and I were evacuated from our home due to a wildfire a few years ago. There was little time, and we just had to grab the few things we could fit in our Mazda and hit the road! Got the pets, her wedding dress, a few photo albums... and the Sega Saturn Virtual-On Twin Stick.
I'm... not particularly proud of that decision, in hindsight. But at the time, when I racked by brain in a frenzy to think of the things I didn't want to lose, it was one of the first things to pop into my mind.
No other consoles, no other collectibles, no other heirlooms, no other
stuff - just the Twin Stick.
I have no idea why we're wired the way we are, sometimes
