On top of all the subjective emotional things, I can clearly see a difference in typing speed and accuracy. I do typing speed test from time to time and it was constant for quite some years, until I got a mech. When I got another (better) mech it got even better still. If you touch type and you are already fast, the tactile feedback of switches really closes up the feedback loop a lot better. Your fingers know you screwed up, before your eyes have to see the mistake. And it's also easier on my hands for some reason, but may have more complex causes.
