I don't know what is going on, but I think for almost every switch on almost every board I have, GMK (as of this morning) is the worst option. Feels the worst, sounds the worst. I'm not ready to sell them all off yet, but I'm seriously considering it. The biggest moment of this discovery was when I compared a cheap custom WASD set against my GMK Dolch set. The cheap OEM just sound and feel so much better to me. WHAT IS WRONG WITH ME?
This is a result of the coolest damn hot swap sockets on Earth. Why didn't I go this route earlier?? I've been able to test a full board with 62g zeals, 67g zeals, cherrystotles, pale blue box Kailhs, purple Kailh pros, and newly tooled Cherry blacks. Each switch with SA R3, fully sculptured SA, Cherry, OEM, and DSA!! I'm about to find the perfect setup for me and it only cost me $50. What a steal.
I have more boards than I really care to count. But I own boards with MX reds, silent reds, blues, blacks, slivers, Gateron blacks, greens, Zealios 62 and 67, Kailh speed bronze, heavy pale blues, all of the pros. Those are the ones I should be able to test more extensively. I also own boards with Matias Click, Black Alps, Buckling Springs, and various rubber domes, including an old Quiet Click and RF 87u.
I have many keycap sets in OEM, DCS, SA R3 (ABS and PBT), SA sculptured, DSA, and Cherry profiles (GMK ABS and enjoyPBT). I'll have to wait until extras for XDA show up on keyclack and I have a set of cubic coming from Massdrop next month.
