Use what ever you like. Mechanical keyboards aren't all good, but some of them can make typing a lot more ergonomic or otherwise feel nicer depending on your personal preferences and typing style. If you use your keyboard a lot, then it's not a bad thing to invest in.

There's no single mechanical keyboard that fits for everyone and if you can't understand why anyone would want a mechanical keyboard that's ok too.

Some keyboards don't have N-key rollover and it's a nice feature for some games for sure.
