That would depend on what switches were in the kmac and what keycaps etc. were used... and most of it would then still come down to personal preference.
I'm typing this on a kmac w/62g blacks, but I use a 55g 87U at work, they're very different beasts. The build quality of the kmac case is clearly better, but aside from that, you can't really compare them. Overall I think I slightly prefer the kmac, but the topre switches are also really nice to type on (and way quieter, which is nice for an office environment).
