Honestly, all you really need is to lube the switches. That’s biggest benefit. A lubed mechanical switch, even the cheapest generic red, out performs anything off the shelf.
Totally agree. You can take a basic mechanical keyboard from Amazon with hot swap switches, lube them. Maybe do a basic tape mod (just put masking tape on the back of the PCB) and get like 85% of the benefit of a high end keyboard. This is what I've done for the rest of my family's keyboards.
