What’s the point of having many of the same keyboards which are practically identical? The layout is the same.
I totally understand ergonomic keyboards (I have Quefrency and Sinc for home and office), but clones of the same 60% Etc. layout with just different case maybe? Key caps are replaceable and if you get a kit with the switches you like, you have more or less seen it all.
Different appearance, different materials, different weights, different build quality, different keyboard features, and so on. For example, some of the keyboards have hot-swappable key switches. Some people just like to experiment with switches. And also the quality of a keyboard affects how the keys will sound. LED lighting or no LED lighting. There are also different types of layouts within 60%. Non-standard backspace keys, right shift keys, etc. As an example, one of the keyboards here features a Fn key to the right of the right Shift key.
Lastly, these are a form of self-expression mixed with personal comfort tastes.
