The return was from about twice the altitude of the Blue Origin booster, with a vehicle that's significantly larger and more powerful. I don't have the numbers for the aerodynamic stresses, but I'd be pretty surprised if that was the case.

Here's a comparison of their flight trajectories - http://i.imgur.com/ATkpdAX.png

And here's a comparison of the vehicles - https://i.imgur.com/zrLWBLJ.png

I don't want to take anything away from the ridiculously awesome achievement of Blue Origin, they have the record for first landing of a reusable booster from edge of space and good luck to them.

The booster is not orbital. It's on a ballistic, suborbital flight just as for the Blue Origin booster. The second stage goes to orbit and note that they are not trying to recover that one at all, let alone land it.

In fact, the SpaceX booster does several deceleration burns in space, and so experiences less aerodynamic stress than does the Blue Origin booster, which actually flies faster, according to the article I linked above.
