If we're talking aboput what would be a "good" design, the answer is that neither the variable stop nor the variable ratio designs actually achieve the equivalent of a manual system. Which gives the pilot the 'real feedback' as to what he's doing to the aircraft. (the goal in artificial feel system design often boils down to "trying to make it feel like a good, manual, aircraft)
The ideal would be a system which restricted the travel of the pedals as it restricted the travel of the rudder (which is basically the variable stop design)
while also causing the force level to achieve the maximum travel to be broadly consistent (which is what the variable ratio does). Unfortunately, trying to meld both systems would undoubtedly yield a rather complex and unreliable design.
Omitting either part of the "ideal" gives a potential for poor feedback, and possible handling issues; I'm not sure the balance of advantage lies with either approach.
