Certainly, if you have the funds, a gen dial is always the way to go. That said, 1 could also make the case that if you are going to spring for a gen dial, you would be crazy not to couple it with a gen Rolex movement (as opposed to a conversion using aftermarket parts).
However, if, like me, you prefer the exotic (Newman) dial over the standard fare, a gen, being so costly/rare, is not an option. In that case, I think a very credible project can be built around some of the better aftermarket Newman dials available
