Durock (JWK for PrimeKB) Alpaca or Durock POM Linear: the long answer
Specs first, since the feel gap is what you notice in the first minute of typing. These are two JWK / Durock linears, so neither one puts a bump or a click in the way of the press. At bottom-out they sit 1.5 g apart, 63.5 g against 62 g, close enough that lube and housing will decide the feel before the spring does. Actuation lands at 2.0 mm on both, but the Durock POM Linear bottoms out 0.3 mm sooner, 3.7 mm against 4.0 mm. Neither one out-feels the other on type, so the small differences in the table are where the decision lives.
What the table cannot tell you is how either one lands in a room. Put them through the player above and the Durock (JWK for PrimeKB) Alpaca lands as smooth clacky-bright bottom-out, benchmark clean where the Durock POM Linear lands as deep rounded POM knock. The usual caveat applies. Nothing here is a studio recording; both packs are synthesized from published specs, and the players say so.
On price and practicality, both are premium priced. Both arrive lubed from the factory, which is one project you can skip either way.
Who buys which, then? One switch takes every axis we score: the Durock (JWK for PrimeKB) Alpaca is our pick for gaming, for typing and for a shared desk.
