Topre Silent 45g (Type-S) or TTC Silent Bluish White: the long answer
This pair has a fit problem to clear before feel or sound matter. The Topre Silent 45g (Type-S) 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. Both arrive lubed from the factory, which is one project you can skip either way.
That leaves the stroke itself. Both are tactiles, so both raise a bump close to the point the press registers and the argument moves to the numbers. Spring weight barely separates them, 3 g at actuation with the Topre Silent 45g (Type-S) on the firmer side, which most fingers will not register. Neither the trigger point nor the depth matches: 2.0 mm to actuation on the TTC Silent Bluish White against 2.2 mm, and 3.5 mm of total travel on the TTC Silent Bluish White against 3.8 mm. Neither one out-feels the other on type, so the small differences in the table are where the decision lives.
What the table cannot tell you is how either one lands in a room. Played back to back, the Topre Silent 45g (Type-S) is muted 'puc': the thock, whispered against soft dampened 'puc', bump intact from the TTC Silent Bluish White. 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.
All three questions get different answers on this pair. Fast inputs: the TTC Silent Bluish White, because this axis is nearly a tie, and it comes out ahead only once the scoring is added up. A long draft: the Topre Silent 45g (Type-S), since its keystroke stays consistent and comfortable across a full day of writing. A room with other people in it: the Topre Silent 45g (Type-S), as its dampening keeps the sound from carrying across the room. Whichever way you land, listen to both above with the volume trims matched before you spend anything.
