Two notes from someone who has been using many keyboards for many years now:
* ABS vs PBT keycaps: I disagree with the author. PBT is not obviously better. I prefer ABS keycaps, because most PBT keycaps have an aggressive texture, which is unpleasant to my fingers. Mind you, it's something I notice after days/weeks of constant use, not after a minute or two.
* Switches: as I discovered, even the "same" type of switch might have a different feel to it. As an example, Kailh brown switches come in opaque and clear varieties and have a different feel. I really prefer the opaque ones.
