Performance and durability in either of these engines are pretty much up for grabs. Performance depends on how their tuned. Durability will most certainly reflect how their driven. They all have their advantages/disadvantages.
DOHC can offer good hp/Liter, but you pay the premium in parts, and overall dimensions.
SOHC could be said to be inbetween. Lesser parts keep the cost lower, and overal dimensions a bit smaller.
OHV (pushrod) its a bit trickier to tune (control of valves). They make it up for its efficiency in space, and cost (especially in a V engine).
