I think Vandals take the cake for best design that doesn't interrupt the keycap functionality, probably even across all makers. The profile appears to be very in-line with the MX OEM profile (I think?), with the majority of the detail being so fine/subtle that it wouldn't have much impact on the overall feel of the cap. And every way you interpret the different aspects of the keycap (design, purpose/function, etc) all ring true in relation to the vandal name/meaning, so just excellent overall execution from that artsy standpoint (that HP/PD may or may not have had in mind when he was creating the design) as well.
DAMN SHAME IT'S MX ONLY THOUGH, I GUESS HE THOUGHT VANDALIZING A TOPRE KEYBOARD WITH ONE WAS TAKING IT ALL A LITTLE TOO FAR~
