There is (or was?) a Dutch keyboard maker called Wooting who has been offering alternative switches like optical and hall effect switches for a few years. I owned their Wooting One TKL and it was really nice. They always had issues with availability, and AFAIK they never offered a 70% HE keyboard, so I ended up with a Keychron with yellow mechanical switches. I still think those optical or HE switches are the best, and it was a bit sad to see that small Dutch company not getting their products out of the door.
Edit: Thanks for the corrections in the comments below.
