There is nothing inherently wrong with either system, but both are subject to all of the parts that make up the system. Newer trucks have diaphragm pressure plates while at least my Jimmy, has a Borg & Beck 12" pressure plate. I don't find the mechanical clutch to be too difficult, but all of the linkage is subject to wear which changes the geometry and adjustment. I completely rebuil the linkage in my truck and it made a huge difference. I've worked on many hydraulic clutches and the feel is dependent on the pressure plate, the master cylinder diameter and throw, the clutch pedal linkage/pivot ration and the diameter and throw of the slave cylinder. Making an all encompassing statment about the inferiority of hydraulic clutches is like saying hydraulic brakes like accurate feel as well and we should return to mechanical brakes... FYI it is still against the law, technically, to drive barefoot in Texas because mechanical brakes got so hot that you couldn't keep your bare foot on the pedal.
