They both are extremely bright and reliable, but I think the Sigma looks more stylish, and it has three modes instead of the Planet Bike's two. The Sigma's clip-on clamp also looks a bit sturdier. They are both great taillights, but I prefer the Sigma a bit more. I've had the Sigma for two years now, and it hasn't failed me yet.
