That is assuming all else is equal, (a.k.a. testerone levels, good pc muscle, healthy diet etc.)
As Gprent said, arteries deliver blood, veins drain it off and return it to the lungs/heart for re-oxigenation and pumping.
Guys with absolutely smooth (no veins or areries showing through skin) can have erections as firm as guys with very veiny penises.
The difference is, after some sensible PE program you will probably have a more efficient delivery/drainage system.
If the veins/arteries also become raised at shaft skin surface you will 1) have a meaning looking unit, imo, and 2) provide more friction and sensation to your partner during sex. A prominent vascular system will offer more bumps and ridges to your partner while you are stroking.
