Which paint?

[swamp rat]

If there is any paint guys out there i'm trying to figure something out. The paint supply place says i have 2 choices for a single stage paint in the 518 Med Green color code, (altho they say its now called Meadow Green).

One is a DCC that is a Urethane base, the other is Delstar that is an acrylic Enamel base, my main goal after laying down some K2 primer is to paint the inner kick panels, floor after repair, and the door jambs and the inner part of the front fender at the top where you see the color. They said whatever i choose the rest of the truck will have to be painted with the same paint...

Which paint should i choose? does it matter?

I am assuming that the original paint is Single Stage so this is why i'm at these 2 choices, this is not a show truck.
