Good question, and very relevant.
The sole reason I am typing on DCS right now is that they are hands-down the best keycaps for my worn-in pre-tooled Browns.
The pre-tooled Browns are terrible when new, very scratch, ping, chalky. But when worn-in they become more buttery.
Thick PBT keycaps just kill the limited tactility and feel of the switch. And thin PBT isn’t usually a quality keycap. OEM-profile is too tall and wobbly on stock Cherry switches.
So they’ve got to be ABS, and they’ve got to be short. There’s GMK, but I tested it alongside DCS and DCS beat it hands-down in terms of sound. GMK is sharp, chittery and high-pitched like an AR-15, DCS is lower and clackier, or even thockier if it’s WYSE.
As everyone will tell you, the thin DCS in particular lets you feel the full tactility of less-tactile switches that are drowned by heavy PBT keycaps.
So, long-story short, DCS sounds better and feels better with pre-tooled Cherry Browns. I also have DCS Sleeper accents on a keyboard with Everglide Jade Greens, and they are okay there - another light tactile. So they are the best keycaps for factory Browns and okay with somewhat heavier tactiles like Jade Green.
