People wax poetic on all the perceived differences between the increasingly ludicrously named switches, but in my experience, if you're a fast typist, you just don't notice it while you're typing. And that's a good thing. If you're constantly distracted by the feeling of your switches, you're probably not getting much work done.
It's easy to get choice paralysis, so for my unsolicited advice: decide whether you want linear or clicky. Get whatever MX linear you can find for the former and a buckling spring (Unicomp) for the latter, and stay away from the absurd (and expensive) rabbit hole that is mechanical keyboards.
(Yes, I omitted "quiet tactile", aka browns. That's because they don't feel particularly tactile while actually working; they're more like gummed-up linears. But if you really want something in this vein, look at Topre Type S keyboards. They're really just fancy rubberdomes, however, and you'll pay a pretty penny.)
