This does not look like the rubber dome Monterey keyboard that I have, the K208. I would think that this one has Monterey switches.
The Monterey switch feels a lot like a Cherry MX blue switch with a much more pronounced bump. There is more resistance when encountering the bump. Unlike the Cherry MX blue, it has no hysteresis. I find it to be better than ALPS on off-center key presses, but I find the Cherry MX blue to be more comfortable.
The difference in layout on the Chicony 5181 from this one is that it has a small backspace key and the \ key next to it. With the Chicony, what switch you get is kind of a gamble.. it could be ALPS instead of Montereys. The biggest flaw with the Chicony is that the case is very creaky. The spacing between key groups is pretty standard, so the PCB/plate assembly can be transplanted into another case. I recently got a winkeyless Cherry G80-3000 case just for this purpose. I just need to cut the edge off the plate and some plastic so that the plate will fit.
