Switch choice changes the entire feel of a keyboard. Linear switches are smooth from top to bottom. Tactile switches give a small bump when the key actuates. Clicky switches add both a tactile bump and an audible click.
For quiet offices, linear or tactile switches are safer. For gaming, many people prefer linear switches because they feel fast and consistent. For typing, tactile switches can make each press feel more deliberate.
There is no universal best switch. The best one is the one your fingers enjoy after a full day.
