Tanaka (KU) B2 was my jumping point, that thing was rough, so many low spots ..... But it taught me a lot about caring, maintaining, sharpening, polishing, etc. and at that price I wasn't too hesitant to try diffrent different things, the total experience gained was worth many many times that of the knife imho.
For practical purposes I think the Kaeru is hard to beat, tough, (mostly)stainless, low maintenance, and the profile is stellar. But it also the most right handed grind of the bunch mentioned. One of those knives you want to reach for all the time without thinking.
Between Mazaki and Munetoshi, I preferred the Mune steel a lot more, I have the "Charcoal White 2" Maz steel and it didnt really impress me at all. The Mune steel is harder, crisper, but still felt great on stones, winner by my books.
Tanaka Ginsanko are light and thinnish, my fav stainless.
Another knife to add to the $200 class is probably the Ginga in #w2 and swedish stainless, those are pretty great if you like the lighter, thinner, less heel height.
