Actually I am trying them right now.
Using 32 steps with RAMPS board on X and Y axis (removed the middle jumper to enable 32 steps and also had to increase the steps from 80 to 160 on both axes).
Quiter than 4988s for sure.
Not quiter than my TMC2100s. More like a very silent 4988. I can't hear the steppers while using TMC2100s, I can definitely hear them with these.
Works cooler than TMCs and probably cooler than 4988s. I have no idea if they are as stable as the 4988s but they definitely are more stable than TMCs.
