It really is a personal preference.
While it does seem the majority of users prefer the two piece keycaps, personally I don't like them. To me, the only way to type is buckling spring with single piece caps.
The two piece caps to me feel mushy, imprecise, and muted somehow. They offer more of a "clacky" sound rather than that "clicky" sound I like, and the ping doesn't come through as much, which is disappointing.
The feel is much like I remember my old Dell ALPS keyboard feeling, not like the clean clear and crisp tactile feel of the single piece caps.
I'm trying to find somewhere to get a full set of grey keycaps (not ivory/taupe) for my new Unicomp Classic that are single piece rather than the two piece caps, as I am really not liking typing on it the way it is...
