The old black ALPS CM switches in my Dell are tactile but not clicky (though you hear plenty of 'clack' from bottoming and topping out). I would say they are good but not great... a bit firm but non-fatiguing.
I do believe the Matias switches are the best ALPS made today (and probably the best in many years). I also have a MiniTouch with 'white XM' switches, which I bought with the intention to convert it to Matias switches. Not sure about doing the conversion now that I have a mini MQP on order. OTOH putting the Matias clicky switches in there might be a lot of fun.
BTW, the Ducky ALPS boards are said to be of poor construction.
Looking at older ALPS switches, some of the best-loved of them are the blue CM, the salmon/orange, white CM, dampened cream and white fukkas. Matias used the fukkas in their own boards until they went out of production; their new switches are basically better versions of the dampened cream and white fukka switches.
Honorable mention goes to the Monterey 'blue' switches, which are only sort of Alps-like, but have a very nice clicky tactile quality. Some MiniTouches and I think Chicony's have them.
