hiro AS is carbon not stainless..
carbonext is thin and narrow, i would not consider it a workhorse.
tanaka g3 is excellent steel, but fit & finish is rather horrible, it's a good workhorse but be prepared to get some work done, it is definitely not thin like the blue#2 version (a good thing if you can thin it yourself). i owned both at one time.
aeb-l takes a nice edge but retention is lacking (speaking from experience with dt itk)
for simplicity and not much work needed, i like the mac pro recommendation, the handle is quite good.
