The 2V rockers are far more robust. As with everything they will wear out eventually, but nothing like as quick as the 4V.
Oil feed is better and the chroming seems to be of better quality.
Main problem with 2V rockers, that causes them to wear abnormally is valve clearances. Spec's are tight and if they are done too tight the rocker gets a hammering.
