Wow, you've picked a wide variety of options.
Of them, the Tanaka is my favorite.....but:
The Tanaka is full carbon, the Tetsuhiro and Hiromoto's are stainless clad carbon core, and the two Artifex's are both stainless.
But, the two Artifex's are about as polar opposite stainless steels as you can get.
If you're okay with a full carbon, wa handle...get the Tanaka...you won't be unhappy. But, the others all have something to bring to the party too.
