NiZ EC 45g or Topre 30g / 35g Electrocapacitive: the long answer
Before anything else, check that both of these will go into the board you own. The Topre 30g / 35g Electrocapacitive does not use an MX style stem, so it will not drop into a standard hot-swap board or accept ordinary MX keycaps. The NiZ EC 45g is mid priced, while the Topre 30g / 35g Electrocapacitive is premium priced. Factory lube on both, so the smoothness you hear in the player is roughly the smoothness you get.
The specs are the smaller half of this pair, but they are not nothing. The spread at actuation is 15 g, 45 g on the NiZ EC 45g against 30 g on the Topre 30g / 35g Electrocapacitive, which puts them in different weight brackets rather than two shades of one. Both are tactiles either way, so each one puts a felt event in the middle of the stroke. Same depth, different trigger point: 2.0 mm on the NiZ EC 45g against 2.2 mm on the Topre 30g / 35g Electrocapacitive, both inside 4.0 mm. Same stroke character, so the spring is the fact to weigh.
What the table cannot tell you is how either one lands in a room. Through the A/B player above, the NiZ EC 45g comes through as thock-lite: softer, lighter take on the Topre voice, while the Topre 30g / 35g Electrocapacitive reads as feather-light softened thock. Worth repeating: the audio here is a simulation built from specs and community descriptions, not a recording of either switch.
This one genuinely splits. The Topre 30g / 35g Electrocapacitive for games, because the two are close enough here that either works, and our scoring gives it the nod by a hair. The NiZ EC 45g for writing, since nothing about it gets tiring by the afternoon, which is the whole test for a writing switch. The NiZ EC 45g for an office, as it is the quieter of the two once the room is listening. None of this beats hearing them yourself, which the player above lets you do in about a minute.
