But the 3580 is with steel plate, and the 3800 is without steel plate. You chose the original factory, so get one without steel plate to play with.
My 3800 feels better than a stepped keycap. I think so. It's hard to get used to stepped keycaps.
3800 is also cheaper than 3850.
It's ok to feel the mechanical keyboard for the first time. After all, the original factory is still very powerful, although both keyboards have shrunk a lot.
