Here's why
I like DOHC:
It's more flexible in adjustments (see VVT) and in general...is a more efficient design, allowing engineers to do more with less displacement.
Here's why
I like OHV:
It sounds ridiculous with an exhaust (all the chains and valves externally-placed cams make DOHC sound "whiney")
And it's simple. Simple to build, simple to maintain, simple to modify.
Simple also means inexpensive.
Here's why
I like BOTH:
They can both be adapted to a V8...and stuffed into a sporty coupe like the Camaro or Mustang.
Which...I have to assume...is why we're all here.
