I'm happy with the 7 Tanaka knives that have come my way, including a 240 VG10 gyuto. No issues there at all. It's always the gyuto that I keep saying I'll get rid of to make room for the other gyutos that come along, but I can never get myself to take that step. I still like using it. Really nice geometry, handles well (though a bit blade-heavy which I didn't like at first), cuts well and because mine is the VG10 version, it's my go-to stainless gyuto.
I've got a Tanaka petty in blue and another in VG10 - the blue cuts much nicer than the VG10 and, possibly due to weight distribution with its thinner heel-to-ferrule section, feels better in the hand. If the petty comparison is anything to go by, I'd expect the blue gyuto to be better than the VG10 gyuto.
The only Tanaka I've had some issue with finish-wise has been a KU nakiri. No issues with anything from the damascus line. The handles, well, they're functional but definitely not fancy. I think the ferrules on the damascus line are all horn - I think it's just the KU line that has plastic ferrules.
No idea which ones I got from 330mate and which ones from metalmaster, but I have bought from both of them. I expected standard shipping to take a while (up to a month), email response was non-existent, but I got the knives and I'm happy with them. My Tanaka blue petty is actually my favorite petty to use - I generally like it better than my Takeda, for example.
