Which mechanical keyboard is for me?

(More to the conclusions)
If you’re a gamer, I would recommend the red switch. For typing, blue switch is the most favorite but also the noisiest switch in Cherry MX variants. Brown can be a hybrid option between gaming and typing despite it’s tactile, but red is still the most silent compared to other Cherry MX. Want the most silent and comfortable feel for typing? Then you can choose electro-static keyboard (such Topre switches) but far more expensive than mechanical Cherry MX switches. Older keyboards like IBM model M with buckling spring (mechanical categorized) switches are cheaper and as comfortable as topre but it’s the noisiest of all keyboards, even noisier than Cherry MX blue switch. May price under $100, but they’ve become extinct that they are over 30 years. Also buckling spring keyboard weight about 4-5 kilograms.

Topre:
Most comfortable to type. But only have few aftermarket keycaps, difficulties of install/uninstall keycaps

Cherry MX:
Most common mechanical switch, customizable keycaps. More noise compared to other switches (compared to rubber dome, scissors-switch, chiclet, etc.).

Buckling spring:
One of the most comfortable to type, but extinct, noisiest. A legendary.
