Welcome.....
If one is shave ready i.e. hand honed for you
that is a tie breaker.
Other than that when you look at them ask which
one floats your boat.
As for stainless .vs. carbon steel it does
not matter a great deal. Carbon steel
does edge out stainless on the hone and
hold an edge a little bit better but for some the
corrosion resistance is the key. Most of us
would be hard put to tell the difference if it
was not for the marks on the tang. With modern hones
the difference is 10 vs 11-15 hone strokes and
since I tend to always give em 20 again
this is a don't care.
