rear disc brakes vs rear drums

Again, intended use applies.
For a HiPo vehicle that you are going to use the brakes to the edge of their envelope, 4 wheel disc brakes should be on your menu. Rear disc brakes do not have the weight or dynamic penalties imposed by drum brakes. The cooling and fade resistance is also superior. Oh, and yeah, they look cooler, which is about 95% of the reason I install them at work.

Are they easier to work with? Are you including your emergency brake into the equation?

I can understand where some folks get confused by more parts to deal with, but I can do a drum brake job just as fast as a disc job. I'm a little older, so I probably have some extra practice. (Don't get wound up, just poking a lil fun).

For most folks, the rear drum set up when assembled properly will do just fine. Remember the whole "locking up the rear brake" thing mentioned? It means your brakes are better than your tires. (given other factors like weight transfer, brake bias, tire sizing, et al.)

Oh, and Wracks, put an adjustable prop valve in your system and spend the time to tune it and YOU'LL be blown away by how good your brakes are.
