Well, on first glance, I was taken in by the Practical Pro's fake rayskin. Then I took a closer look, and was forced to admit that no one has anything on Hanwei's rayskin molds. The color's well matched to the application, although the consistency of that color is one of the giveaways.
Dashizame style tsukas are never particularly comfortable anyway in my opinion - rayskin is hard and abrasive, and it's one of those nasty things that can cause you to become allergic to it with prolonged exposure. I'd have to imagine that the plastic might be an improvement in initial comfort, at least.
(The plastic on the Hissatsu is actually some sort of Kraton relative - it has a fair amount of "give," while the plastic Hanwei uses is somewhat harder.)
