I love my Cherry MX Browns and hope the switch isn't going away. My main board is a Max Keyboard Blackbird with browns. It replaced a CM Storm QFS (also with MX browns), because I missed having a back-lit keyboard, and I loved that the keycaps were double-shot. Before that I had a CM Storm QFR with MX Blues. I liked MX Blues, especially the sound, I just didn't like gaming with them.
I have multiple RSIs, so a low actuation force is better for me (haven't had a chance to try Cherry MX reds, yet. I tried one of those tester kits, but it was useless). I like being able to have keycap options, so I haven't bothered to check out Topre, and I've tried but didn't enjoy Alps (hubby's pricey Datamancer "Executive" keyboard - which he set aside for my old CM QFR with MX Blue!).
Ultimately, though, I'm waiting on AcidFire's keyboard project.
