Quick test. The soft click is the same. Weight feels about the same as a blue, but because of the softer click, it feels slightly easier to press down. I almost want to say it's like a slightly louder brown. Pushing slowly, it does feel easier to actuate than a normal blue.
I don't have a fullboard to swap around a full set, but I feel like it would be a perfect way to have softer blues.
Edit-Guess Lysol beat me, but his blue/brown baby analogy is spot on
