Verdict
Durock and Durock (JWK) are selling the same stroke here, and on paper they are selling it at the same weight. Both springs measure 48 g at actuation and match at bottom-out too, so weight will not settle it. What really separates them is sound, with the Durock Dolphin tending toward muted deeper patter, low-pitched hush and the Durock (JWK) Silent Alpaca toward muted cushioned patter, the silent-linear standard. Our picks: the Durock Dolphin for gaming and a shared office, the Durock (JWK) Silent Alpaca for typing.

Durock Dolphin or Durock (JWK) Silent Alpaca: the long answer
Take the mechanical side first, since that is where this pair separates. Every force row in the table above reads the same on both sides, 48 g at actuation and 62 g at bottom-out. These are two JWK / Durock linears, so nothing sits between the top of either key and the bottom. Travel is a straight match, 2.0 mm of pre-travel and 3.8 mm in full on both. On paper these are the same switch. The difference has to be somewhere the spec sheet does not reach.
Sound decides more of these arguments than force curves do. Through the A/B player above, the Durock Dolphin comes through as muted deeper patter, low-pitched hush, while the Durock (JWK) Silent Alpaca reads as muted cushioned patter, the silent-linear standard. Both carry factory dampening, so this is a contest between two of the quieter switches you can buy rather than a loud one against a quiet one. One caveat we repeat wherever a player appears: no studio recording sits behind either of these. They are built from what each maker publishes and what the community reports.
On what they cost to fill a board, both are premium priced. Both arrive lubed from the factory, which is one project you can skip either way.
So who should buy which? For gaming we lean toward the Durock Dolphin, because this axis is nearly a tie, and it comes out ahead only once the scoring is added up. For long typing sessions the Durock (JWK) Silent Alpaca makes the stronger case, since it holds the same feel from the first hour of writing to the last. And if your keyboard shares a room with other people, the Durock Dolphin is the one we would trust, as a dampened bottom-out is the only version of this that a shared room forgives. Match the trims above, play both, and trust whichever one you keep replaying.
