Verdict
Stroke character is a tie. Two tactiles feel alike under a finger, which pushes the decision onto the rows below the type row. Only one of them is silenced. The Gazzew Boba U4 has the pads, and in a room with other people in it that beats every other row here. Weight is hard to separate here: each is rated 62 g at bottom-out, and that is the only measuring point with a published figure for each. 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 Gazzew Boba U4T is the answer only to a question our scoring does not ask.

Gazzew Boba U4 or Gazzew Boba U4T: the long answer
Take the noise question first, because it is the real gap here. Two different voices: near-silence with a firm tactile knock underneath on the Gazzew Boba U4, the reference thock: deep, full, immediate on the Gazzew Boba U4T. Only the Gazzew Boba U4 is pad-dampened. That removes the top of the bottom-out entirely, which is a bigger change than any number in the table above, and it is why the Gazzew Boba U4T is the one people hear through a wall. Both packs are synthesized rather than recorded, so read the comparison as a faithful sketch of each voice and not as a measurement of it.
That leaves the stroke itself. Actuation lands at 1.7 mm on both, but the Gazzew Boba U4T bottoms out 0.8 mm sooner, 3.2 mm against 4.0 mm. These are two Gazzew Boba tactiles, so each one puts a felt event in the middle of the stroke. They land on the same 62 g at bottom-out. That is the only measuring point with a figure for each of them, and actuation is exactly where two switches matched at bottom-out tend to separate. None of these gaps is large. Stack them up and they still point somewhere, but gently.
On price and practicality, both are premium priced. Factory lube on both, so the smoothness you hear in the player is roughly the smoothness you get.
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, the honest answer is that either would do, and it wins on a margin too small to feel. On typing feel, it holds the same feel from the first hour of writing to the last. On noise, the pads stop the bottom-out from traveling past your own desk. That leaves the Gazzew Boba U4T to anyone who preferred its voice in the player above, which is a good enough reason on its own. Whichever way you land, listen to both above with the volume trims matched before you spend anything.
