I was strictly Topre for a while with my HHKB, RF 87u, and FC660C, but I found myself missing MX after a while, so I got back into it. My EDox is my DD for now as I'm still trying to learn the layout, but my 87u and HHKB are still my favorites by far. YMMV greatly when it comes to Topre, they all feel different from eachother, and even then, topre as it is feels completely different from everything else.
