First thing: you are right-handed, aren't you? Because all knives I'm speaking about are more or less strongly right biased.
The Misono at 210mm is rather narrow.
A very nice, finely grained steel, but a tad softer than your Herder 1922.
You may consider the Masahiro VC instead, which has the harder steel as well, quite close to Aogami #2. Not with Misono's nice F&F, though. That said, all Misonos come with a weak, overly convexed factory edge due to excessive buffering. But at this price point all Japanese knives require a good stone sharpening before use. In the case of a Misono you can't just follow the factory edge, though.
If it's important to you: Misonos come with a spear point tip, elegant but vulnerable. The same as your Herder, but that one comes with a relative thickening at the tip. Masahiro has a classic Japanese low tip.
Another option were the Suien VC, made of monosteel Aogami #2. Requiring a good stone sharpening to attenuate its extreme asymmetry and ease its protruding shoulder. So, with both the Misono and the Suien, first thing to do is taking it to a coarse stone. To me, the Suien is the most comfortable one, but only after some love.
