Finalmouse Phantom vs Poseidon clicks/switch comparison (and some rambling)
A commenter asked for a comparison, so here it is.
Phantom and Poseidon both use Kailh GM 8.0.
The Phantom has more post travel and sounds deeper than the Poseidon.
Kailh switches have always had a fair bit of inconsistency between switches, so it's hard to draw conclusions from this sample size of one.
GPW and G305 use Kailh GM 4.0.
GPW at the end uses Kailh silent switches.
If you have questions, feel free to ask :)
