On a recent facebook poll amongst my non knife nerd colleagues...
The vote was almost universally Global!
Not owning any of the Kato / Shigefusa ... my favourite cutter is my Toyama.
But if I had to choose most respected... I would say whatever JKI recommend for me.
And I was just coming by to say : don't buy Global or Shun thinking you'll have a feel of a J knife. I did that... Global. Don't. From there all should be fine.
Otherwise, don't be too afraid to follow your instinct and try something that pleases YOU - NOT what people will tell you to buy. You can ask for advice and you'll get very good advice here, but in the end make your own decisions.
If you don't like a knife, stop using it, take pictures, post in BST. Someone usually manifests. I had 860$ of about new knives I didn't feel I should keep based on my preferences which had developed quite a bit. Sold them for about 720$. I think the 140$ lost was the best investment of my life, if you look at it from the right perspective.
Edit: well, of my knife life.
