I still have a lot to experiment with. So far I've tried the standard MX switches - blue, brown, red and black. Linear switches are just not for me, I know that much. I'd have to say that brows suit me best, because I type a lot and they are quite comfortable for that.
Topre seems very, very appealing. However, they are pretty expensive and a lot of people say that it's just a glorified rubber dome. However, I don't really care what others have to say, I'll have to make up my own mind once I try them. And even if they do feel like rubber dome, that's not really a bad thing. Because still to this day, I still type fastest on a crappy Logitech than I do on my MX Browns, and I have no idea why. So maybe Topre will be beneficial, who knows.
I've never owned a full sized mech before, I started out with TKL and I still like that form factor. I also really like my Poker II so I dunno.. I just like the way the Poker looks and feels. I actually have my eye on a Race right now with MX White, so I may give that a try.
