Don't have those but I do have this one:

It can be had in 270 as well. I love it, reach for it often and kick myself for not buying a sujihiki sooner! The SK steel is nice. It is resilient and sharpens readily. I did do a little hand sanding on the spine and along one spot on the tang. Nothing major just something I noticed and was easy to correct so I did it. Nice asymmetric grind that performs very well.
I think some these SK steel and the like knives are something of a hidden gem as performance for price goes.
