Generally speaking, any camera strap will allow you to carry your gear in some fashion but the question here is "how". The strap that Canon (or Nikon, Sony, etc.) provides is designed for over-the-shoulder or around the neck carry. Generally, that strap is on the thin side, affixed "permanently" to the camera and advertises the camera brand. The PD strap is longer and can easily be adjusted to provide shoulder or neck carry, as well as cross body. The PD strap is wider than the manufacturer provided one (about double), can easily be removed from the camera via PD's quick attachment anchors (and those anchors can be attached to virtually anything you might want to carry) and there is no camera manufacturer logo.
I prefer cross body carry, and the longer and wider PD strap easily accommodates that while distributing the camera & lens weight more evenly. Occasionally I like to remove the strap entirely for a little more freedom of motion, or attach it to the 100-500 lens to remove any strain on the camera to lens mount.
Basically, it comes down to personal preference, your needs and how you like to work.
