Powdercoat is a more pricey but is a good way to go. If my customer has time to leave the car for a few days, then I would powdercoat, but most want it done overnight so I paint but still take everything apart, clean, prep and use quality products. Check the results:

@Mike, nice work!

180 how does the paint hold up over time?

Yeah, people want it done quick. I have lots of exchange calipers for corvettes and camaros, but only one set of akebonos, because demand is a little too low to justify the expense. I can do local peeps in a day.
