I could not find the speed on either one of those clippers. Speed for me personally is a must because the fast your clipper goes the nicer the cut and you dont have to go through the same spot twice. I was also looking at something quiet, but no matter what there will always be sound from the motor.
I ended up buying a Andis super two speed and LOVE IT!!!! I have heard good things about Ostar brand as well but not familiar with Whal.
I know this did not help you decide between your two choices but I hope it helped anyways. Once your there look at the speed it makes all teh diff when grooming.
good luck
