They used to be a commodity but are increasingly a colorful form of self expression.
My old daily driver was a Leopold FC660C that's heavily modified with:
A hasu controller for full programmability with QMK firmware

I also have:

SA profile keycaps
a gergo low profile ergo keyboard
lubed linear kailh choc low, with 45g springs
silent tactile gateron yellows with gazzew u4t stems and 65g springs
