Good ball links will outperform all the other types hands down, especially over a long time as they do not wear like clevises (the pin wears and also the hole they goe thru enlarges with time). The worst is the Z bend, they will soon become sloppy due to the wear they make on the control horns which will soon become quite enlarged. For simplicity, the L bend with the plastic keepers work okay on sport planes and do not create the wear the Z bend causes.
