razer mechanical sucks. sold my previous widow away, too plasticky build, uneven key presses.
unicomp is awesome. very basic. no frills, no backlight, no macros. the typing feel is untouchable like the original ibm. can be a lil heavy-fingered for gaming though, those coming from membrane need some getting use to. thoroughly recommended.
just got the latest corsair k95. so far the most brilliant for gaming. using the sweet spot cherry red switches. the backlight & macros are unmatched. keys are mounted raised on flat alu platform, making cleaning a breeze. so much thought put into this baby.
