I assume you didn't really try to understand what you're talking about.
Generally, Pentax bodies feel a tad more refined, even if you compare a D4 vs. a K-5. But thats's the first impression (partly because they are smaller), I am sure the Nikons are great when weared down.
Otherwise, the D600 body is above a K-5 body, on par on most things and beaten by a few (#card slots, uncompressed hdmi out, better AF.C, 39 point AF with 3D tracking, viewfinder, rgb metering sensor, tethering, sensor size). The K-5 wins for its silent mirror.
But if you talk about a deceiving body then you extrapolate the past. Current FF bodies aren't crippled anymore. Which is why they'll extinct APS-C dSLRs. IMHO. At 1599,- Euro in Germany, the D600 does already occupy the niche the K-5 populated at launch.
