Depends on how much time, effort and attention to detail you're willing to invest in the handloads. The big commercial ammo makers load MILLIONS of rounds of ammo a year on state of the art loading machines that probably start in the six digit range and go up from there, and have ballistics labs staffed with guys who's sole purpose in life is to find loads that are safe, reliable and perform reasonably well in the largest cross section of firearms. But the caveat to making ammo to suit every gun is that it will never always suit any one gun. By handloading you are able to make ammo that perfectly matches your individual rifle, not ammo designed to shoot in every rifle chambered in that cartridge.

It's likely that with enough experimenting you could find a factory load that will shoot as well or better than any handload you'd likely work up BUT...you'll be forced to shoot whatever bullet/brass/primer/powder combo the factory is using, which may not be exactly what you want or need. The greatest advantages I see in handloading is that it allows you to make loads that are taylored to suit my rifles using the components I want to use. Secondly, it allows me to load and shoot premium bullets without paying through the nose for premuim factory ammo.

I also enjoy rolling my own. It's enjoyable and the results, when good, are very rewarding. Of course, the flip side is that when you just can't find a load that your rifle wants to shoot it can be downright infuriating.
