Single Stage or Base/Clear??

So after 3 months of trying to pick a color to paint my dart sport, I am 99.9% sure it is going to be black. Now the decision of what type of paint, single stage urethane or base coat/ clear coat. I will also be adding the correct vinyl side stripe and the one on the hood with a scoop. Paint guys..... looking for opinions and preference on the look, durability, ease of care, etc.
Thanks
