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.
TTC Silent Bluish White
TTC publishes no bottom-out force for this switch, so the dashed end of the curve is an estimate, not a spec. Everything up to actuation comes from the published numbers.
Gazzew Boba U4 or TTC Silent Bluish White: the long answer
Start with feel, because it settles most switch arguments before sound comes up. The force numbers do not line up: Gazzew rates the Gazzew Boba U4 at 62 g bottom-out while the TTC Silent Bluish White is quoted 42 g at actuation, two different points on the curve. Neither the trigger point nor the depth matches: 1.7 mm to actuation on the Gazzew Boba U4 against 2.0 mm, and 3.5 mm of total travel on the TTC Silent Bluish White against 4.0 mm. Both are tactiles either way, so both give a finger something to aim at on the way down. The one thing the spec sheet cannot do here is line up the springs, which leaves the player above carrying more of the decision than usual.
Sound is where most people finally pick a side. Put them through the player above and the Gazzew Boba U4 lands as near-silence with a firm tactile knock underneath where the TTC Silent Bluish White lands as soft dampened 'puc', bump intact. Dampening pads are on both, which puts the whole comparison inside a narrow band of volume and moves it onto tone. Worth repeating: the audio here is a simulation built from specs and community descriptions, not a recording of either switch.
On cost and convenience, both are premium priced. Both come factory lubed, so neither needs work out of the box.
Who buys which, then? Gaming goes to the TTC Silent Bluish White, because the two are close enough here that either works, and our scoring gives it the nod by a hair. Writing goes to the Gazzew Boba U4, since nothing about it gets tiring by the afternoon, which is the whole test for a writing switch. A shared room goes to the Gazzew Boba U4, as its dampening keeps the sound from carrying across the room. None of this beats hearing them yourself, which the player above lets you do in about a minute.
