Just from reading the thread I think your main concern is edge retention and it's ability to be touched up because you seem apprehensive about sharpening yourself.. If you are considering shun I'd look into Suisin Inox myself. I've heard good things for the $$. JKI, Korin and CKTG all carry them so I don't think they are something to disregard.
:2cents:
Initially it was about the edge. Which steel might give me give me the sharpest edge and retain it longer. But thinking it over it's not the case any more. It's more about how the knife will perform in my hand. Does it fit my criteria? Since I believe now that any possible difference between high quality steels (e.g. Takeda blue #1 vs Tojiro/Shun VG10) and their ability to gain a degree or two of sharpness over another is immaterial for a "home cook". I believe any VG10 knife will provide more than enough sharpness and retain the edge "long enough" for me.
Can a "home cook" spot the difference in performance between two knives? I'd hope so. Though, in certain cases it can be more subtle. Similar designed knives for example.
Will look into a Susin Inox too. In addition to my 2 other choices (Tojiro DP & Shun Premiers). Thanks.
...and I definitely DO plan to maintain my new knives the best I can (e.g. don't leave them wet, hone/sharpen them myself or get an expert to do it for me). So NO I wouldn't be satisfied with OOTB sharpness. Why would any one who is considering a Japanese knife? A "throw away" supermarket generic brand knife perhaps.
