>This is like debating between owning an SUV and a sports car
Terrible analogy, because most people have more than one knives. It would be more like debating between Trek and Gazelle (the bicycle manufacturer). One offers a vast array of products from lightweight high-end TT bikes, to beach cruisers, to downhill MTBs to upscale steel touring bikes to humble flat-bar commuters. The other offers boat anchors in three styles.
From Japan, for every macro scale knife usage (slicing, chopping, all-purpose, small short bladed knife, boning, etc) you then subdivide into multiple preferences (wa handle, japanese handle, machine made, hand made). Then for each macro scale usage you might have several subtle or not so subtle alternate styles (honesuki/garasaki, deba/yo-deba, suji/yanagi, etc) each with its own strengths and weaknesses. Then you have dozens of different common steel types even from a single manufacturer (the hitachi "paper steels" of which there are a good half dozen one for every taste, vg-10, vg-1, 440c, 19c27, 13c26, various powder steels, etc). Then within each of those you have different style finishing and construction (clad, monosteel, honyaki, honkasumi), and the more cosmetic stuff (hammer finish, dimple/granton, suminagashi, kurouchi, etc.
The Japanese cooking knife industry has basically evolved to overwhelm the consumer with options, which, I guess, to some people, is a bad thing, but for a fan of choice, it's great.
On the other hand Germany basically says, you get a chef knife, a slicer, a paring knife, and a bread knife. We'll make each of these in the same style but, from two steels (x50crmov15 for the "good stuff" and 440A for the shitty stuff) and either a cheap plastic handle or an expensive wood handle. That's a lot easier for some people to deal with - don't give me a choice, don't ask me what I cook or how or where, just look at my wallet and tell me exactly what to buy.
