Get the D-handle right angle Milwaukee, the variable speed one with the removable cord. Easier to replace, and you can get a 25' replacement.
The Hole Hawg isn't as easy to use in my opinion, bad ergonomics. Also the HH is heavier.
The HH has more torque, for sure. Important for a plumber or an industrial/commercial sparky who's going to be drilling a lot of holes for 3" to 6" pipe. In resi, the biggest hole you're gonna punch is for the service entrance mast--and only one per house.
Porter cable makes a good R-angle. Gets in the tight places. Most R-angles are 7-8 amps , which a HH is anyways. I got a 10A 3/4" Milwakee, next step up from a HH, great for blowing 15A circuits, or workin' out yer 'pecks'. oh, those dewalt's have a recall i think?!?

My vote is for the D - handle right angle variable speed reversing Milwaukee. To this I've added the 30" extension and a 33 degree knuckle for the chuck. If you haven't seen one, the tool (drill and extension) looks like an SST jet and is great for offering kids free dental work for those hard to reach molars. Seriously though, I can shoot a line of parallel holes in wood framing from floor to a 9' ceiling without bending over and without a ladder. The 33 degree knuckle puts my shove at the handle.
The right angle, case and tools are available out of St. Paul for $229 and the extension at $229 with free freight from Tools On Sale (800) 328-0457.
