Some key caps have been made to be industrial friendly and layout neutral, like DSA, others are made to replicate a long and lost era, like SA, whose profile was replaced for a reason; even, some are made to be produced at low cost like all the thin versions of OEm profile keys in different materials.
Fortunately for some of us, there are some manufacturers that stick to high quality in both design and manufacturing, that still produce the best profile, Cherry, with a high quality process, double shot molding. It is not for everyone, though, for the cost conscious, low cost OEM key caps are the best, for those that want nice color combinations and use non standard layouts DSA and SA non-contoured sets will fit, The last may give the sense that you are typing in a very old keyboard with an outstanding look, for the those interested in gave their boards a fashion look, contoured SA, for the rest of us, only interested in getting the best typing and the longer lasting key cap sets, Cherry profile, either, old vintage OG sets, or brand new GMK made ones, that may not exactly be the same outstanding quality of the good old Cherry, but they are still quite good. Ah, do not forget that some like the Cherry profile in dry feeling PBT, for those, there are some sets in that material and in Cherry profile.
