Gazzew advertises a bottom-out force for the Gazzew Boba U4T and Topre an actuation force for the Topre 55g Electrocapacitive, so the two headline numbers are not measured at the same point. Compare row by row, not brand claim to brand claim.
Verdict
Stroke character is a tie. Two tactiles feel alike under a finger, which pushes the decision onto the rows below the type row. These are not drop-in alternatives to each other. The Topre 55g Electrocapacitive needs a board built for it and will not take ordinary MX keycaps. Be careful with the force numbers: 62 g for the Gazzew Boba U4T is a bottom-out figure and 55 g for the Topre 55g Electrocapacitive is measured at actuation, so they are not directly comparable. Nothing here separates by use case: the Gazzew Boba U4T is our pick for gaming and for typing, and it is the one that carries less across a room. Take the Topre 55g Electrocapacitive only if you specifically want deeper, firmer thock with authority.

Force curves
Gazzew Boba U4T
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.
Topre 55g Electrocapacitive
Topre 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 U4T or Topre 55g Electrocapacitive: the long answer
This pair has a fit problem to clear before feel or sound matter. The Topre 55g Electrocapacitive does not use an MX style stem, so it will not drop into a standard hot-swap board or accept ordinary MX keycaps. Both are premium priced. Factory lube on both, so the smoothness you hear in the player is roughly the smoothness you get.
That leaves the stroke itself. The force numbers do not line up: Gazzew rates the Gazzew Boba U4T at 62 g bottom-out while the Topre 55g Electrocapacitive is quoted 55 g at actuation, two different points on the curve. Travel differs at both ends, with the Gazzew Boba U4T registering first at 1.7 mm and the Topre 55g Electrocapacitive running deepest at 4.0 mm. Both are tactiles either way, so both give a finger something to aim at on the way down. Neither one out-feels the other on type, and the force rows are measured too differently to break the tie, so the rest of this page has to.
Now the part spec sheets cannot carry: the voice. Played back to back, the Gazzew Boba U4T is the reference thock: deep, full, immediate against deeper, firmer thock with authority from the Topre 55g Electrocapacitive. Worth repeating: the audio here is a simulation built from specs and community descriptions, not a recording of either switch.
This one does not split. Every axis we score points the same direction: the Gazzew Boba U4T is our pick for gaming, for typing and for a shared desk. On speed, the scoring hands it a shorter distance to actuation. On typing feel, it holds the same feel from the first hour of writing to the last. On noise, it is the one of these two you would not apologize for. That leaves the Topre 55g Electrocapacitive 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.
