Drop D makes certain things a lot easier, and other things a lot harder. Playing a regular old triad becomes nearly impossible in Drop D without using the 10th instead of the 3rd. But you can do pulloffs to open strings in two octaves. Of course, you could just use your left hand as a capo in standard tuning and do the run with just your right.
That being said, it feels rather unnatural to me, after learning to play in standard. I'd prefer to use one hand to capo up and tap runs with the other hand than tune down to do those same runs with open strings. Plus, it looks really impressive, no matter how simple the line is, when you have two hands on the fretboard.
