It looks to me like you want a German knife (almost) or a Shun. That is, lots of the advantages of a Japanese knife are not things you describe wanting in your original post. (Some of them are, so I don't wan to be too simplistic about this. Like... a Japanese handle, for one).
That is, the sharper the knife, the more relaxed and "softer" pinch grip you get to use. You primarily use a hammer grip. The J-Knives are lighter and more agile "i.e., easier to point") in part because the lower tip on the profile makes them so; you do mostly "rock chopping" and want a bigger belly on the knife. Rock chopping with a hammer grip and a bigger belly means lots more "powering through", less sharpness needed or helpful, less agility needed or helpful. And a shorter knife with a bigger belly gets rid of one big set of very important concerns that lead people to J-knives. (Mind you, I get there are some edge characteristics that will still be better -- most of those are much more at issue for someone who is sharpening by hand, too. Not all).
Now, you *also* said you were going to experiment with different grips, which might lead to different cutting styles and more use for a sharper more agile knife, so maybe I'm wrong. And you do want a wa-handle, which you'll get only on a Japanese knife. I say this just to prove I'm reading, and let you know that none of what I said above is meant to be construed as telling you what you *should* want, I just want to point out that it may be helpful to do more thinking about why you want what you want. And if you're willing to learn a slightly broader set of knife skills, all my original concerns go away.
That said, from your list, I can't rank them because I've only handled a few of them. Just based on price and past recommendations, and that I think the Tojiro Shirogami is probably more reactive than you might truly be wanting to deal with, I'd recommend the Tojiro DP. On the other hand, given that you might be entirely in this just for a non-western handle, I'd recommend whatever is least expensive and re-think after some time of dealing with it.
PLEASE ignore all of this if it is indeed not helpful to you.
