I have Gateron browns, Cherry browns, Othemu browns.
Cherry browns; feel nice and solid, the tactile bump is superb, least wobbly. (on a VA87M)\
Gateron browns; smoother by a little bit (compared to Cherry), but the bump is less distinct. and is quite wobbly/ loose (on a Team Wolf Zhuque)
Othemu browns; least favorite, but they were the first ones I got, it came stock with the Team Wolf Zhuque, quite decent to start with (full working mech kb for about usd$40 shipped from tb).
I will have some zelios incoming, (thanks to a fellow geekhacker!) will update again once I have them installed. it will also be on the Team Wolf Zhuque, it is a hot swappable keyboard. one of the best ideas there I have seen. build quality is decent, albeit it does not have a removeable cable. might be a minus for some.
just ordered the novatouch, now can't decide which to use in the office and what to use at home.
first world problems.
