So ducky greens are just stiffer blues?
Ducky keyboards use
KSB family clone switches from Xiang Min (Taiwan), customised from the default 60±15 cN down to 55±15 cN for reduced force. (I don't have the exact model used – the language barrier is too great for me to be able to communicate effectively with Xiang Min.)
I have personally never tried a Ducky Alps keyboard, so I have no idea how they compare to vintage blue Alps CM (from Alps Electric Co, Japan) switches. I do know that blue Alps switches are very tactile, so if you can't feel that, you really have destroyed them. Blue Alps CM has a sharp tactile point over a relatively light spring (similar spring to brown Cherry); clone switches typically have stronger springs.
I've heard that white Alps CM (the successor to blues – still vintage switches from Alps Electric) are stiffer so you might prefer those. I don't know the date when Alps Electric introduced their own simplified switches, which (for clicky) were also white the same as the previous complicated switches. Clone switches were simplified from the outset – only Alps Electric ever made complicated switches.
