I had an MG and an early Datsun with hydraulic clutches. Those were so easy to use, there were times I thought they couldn't be working correctly. Then I drove a GMC with a hydraulic clutch for a month or two that was terrible. I decided it all had to do with well-designed linkage and the right strength of return spring. I finally got the GMC to work better, but it was never as smooth as the MG and Datsun. The GMC had 2 return springs.
