It's all about the effortlessness that comes when you do start typing. You want it to be as automatic as possible so you're not wasting any of your attention on it. If a keyboard lets you type faster or with fewer typos, that's a win.
P.S. I prefer the mechanical switches but I had to give mine up for the sake of my wife, who was driven batty by the noise.
I went with Cherry MX browns for a combination of tactile feel and quiet operation. Plus, you can get damper rings for the switches so that the keys don't bottom out, which is the majority of the noise, in my experience.
