The greatest attraction of MX is that the selection of keycaps (pimpmykeyboard PBT keys are awesome) and compatible clones. The biggest drawback is that it's a pretty big and tall key. I hope ML becomes more popular as an alternative.
Cherry also has new low profile MX mount switches too.
But all of these sacrifice travel.
I would expect you to be interested in DSS and the new SA-P from SP.
