As said above by others about drops, that covers most of the big stuff. So in an hour you can hit the story mission, Ascenent Challenge, and Blind Well done. Blind Well with 2 Tier 4 completions gets Petra’s Bounty and the completion there. That is 5 Powerful drops. In contrast on Day 1 of a Flashpoint you can do a Heroic Adventure and finish the Flashpoint for 2 Powerful drops, in a comparable timeframe. A second visit later for a second Heroic Adventure is 3 Powerful drops. With a second visit to DC you can complete the 8 Daily Bounties for Petra and get a 6th drop.

You can squeeze a lot out of it compared to other activities. Not that you should limit yourself if you are just after powerful drops, but there are lots of good reasons to do stuff in the DC if you are pressed for time and not specifically trying to pursue other activities.
