Watch the "brand rates force at" row: these two makers do not measure at the same place, bottom-out for the Gazzew Boba U4 and actuation for the Gateron Silent Brown. Force numbers only compare within a row. Gateron publishes no bottom-out figure for the Gateron Silent Brown, so the figure marked "our estimate" is our own derivation from the forces that are published rather than a rating. How we derive a bottom-out figure .
Verdict
This is a tactile versus tactile contest: the Gazzew Boba U4 and the Gateron Silent Brown share the same stroke character, which makes the smaller spec gaps decisive. The Gateron Silent Brown is the cheaper board to fill by a full bracket, mid priced against premium priced. Weight is nearly even at bottom-out: 62 g for the Gazzew Boba U4 against 60 g, a gap most fingers will barely register. Gateron publishes no bottom-out figure, so treat that 60 g as our estimate. One pick, not three: the Gazzew Boba U4 takes gaming and typing, and it is the dampened one, so a shared room is not an argument. The Gateron Silent Brown is the answer only to a question our scoring does not ask.

Force curves
Gazzew Boba U4
Gazzew rates this switch at its bottom-out and publishes no actuation force, so the marked bottom-out is the spec and the dashed line into it is an illustration of the stroke, not measured data.
Gateron Silent Brown
Gateron publishes no bottom-out force for this switch, so the 60 g at the end of the stroke is our estimate and the run into it is dashed. Everything up to actuation comes from the published numbers. How we derive it.
Gazzew Boba U4 or Gateron Silent Brown: the long answer
Cost is the honest headline on this pair, so take it first. The Gazzew Boba U4 is premium priced, while the Gateron Silent Brown is mid priced. Both arrive lubed from the factory, which is one project you can skip either way.
That leaves the stroke itself. The Gazzew Boba U4 registers earlier, 1.7 mm against 2.0 mm, inside the same 4.0 mm of total travel. The stroke itself is shared: both give a finger something to aim at on the way down. The Gazzew Boba U4 is nominally firmer at bottom-out, 62 g to 60 g, but 2 g is not a gap you buy a switch for. Gateron publishes no bottom-out figure, so treat that 60 g as our estimate. Nothing here is decisive on its own, which is why the sound comparison matters more than usual on this pair.
Sound is where most people finally pick a side. Played back to back, the Gazzew Boba U4 is near-silence with a firm tactile knock underneath against muted light-tactile tap; a whisper with a bump from the Gateron Silent Brown. Dampening pads are on both, which puts the whole comparison inside a narrow band of volume and moves it onto tone. 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.
This one does not split. Every axis we score points the same direction: the Gazzew Boba U4 is our pick for gaming, for typing and for a shared desk. On speed, it wins on a shorter distance to actuation. On typing feel, it holds the same feel from the first hour of writing to the last. On noise, its dampening keeps the sound from carrying across the room. That leaves the Gateron Silent Brown to anyone who preferred its voice in the player above, which is a good enough reason on its own. Before you order either, match the volume trims above and hear them back to back.
