Is there a comparison between aliaz silent vs kailh box silent switches?
No, but I have both. They are very different.
Aliaz is a standard Cherry-like tactility, with the bump somewhere in the middle, following some pre-travel.
BOX Brown has the tactile resistance right up-front, at the top.
The difference in tactility is pretty significant. BOX Silent Brown is more tactile than BOX Brown, which is more tactile than Cherry Brown. Aliaz, on the other hand, is about as tactile as Gateron Brown [not much], and you may lose the tactile bump amidst the dampening material.
Aliaz is kind of "did I actuate the switch?" whereas you will know with BOX Silent Brown.
In testing, I found Aliaz to be good for gaming [especially in 60-65 gr weights], and BOX Brown / Silent Brown to be better for typing. But the tactility may be too much for some. Aliaz may be easier for some people to deal with, and is okay for typing in the 70 G weight.
