Despite the fact that Apple makes both of them, each bud has a totally different design. The AirPods are sleek and functional, while the Powerbeats are sporty and clunky, but with a tighter fit.

If you're using them as everyday buds during your commute or at the office, the lighter feel of the AirPods might be ideal. But if you're going to be working out, the Powerbeats have the upper hand. Their in-ear tips and over-the-ear hooks should help them hold on tighter than the AirPods during intense workouts, while their water-resistant exterior can handle the sweat that comes with the territory. They were made with athletes in mind.
