I'd bet the Pentax 100/3.5 macro is the best of the Cosina rebadges for Kmount because: a) it focuses the "right" way b) it has SMC.
We have three Phoenix 100mm/f3.5 macros in the household They're sharp, but they focus the wrong way, and flare is noticable in the viewfinder. Their only advantage over the Pentax is an included 2-element diopter that makes the lens go to life-size. My M 100mm f4 Macro beats the pants off the Phoenix, btw, and costs about the same. So I switched the diopter; I carry it with the M.
