It's easiest and cheapest, but if you've ever painted a decent sized panel with spray cans you still need some skill there to actually lay a decent coat without it being full of drips, shadows, and obvious areas where the paint isn't flat.
And even if you manage to lay a decent coat you'll still want to have a heap of wet/dry paper on hand to flatten it off before you give it a good cut.
Of course, if you're happy with a 20 yard paint job (looks great from 20 yards away) then just use the spraycans, but if you want it to look any good at any kind of close distance you'll need to put in the elbow grease.
