I've had the opportunity to use headsets from both companies, and own a Vive.

Oculus' devices seem generally a bit lighter and more comfortable, and Valve/HTC's devices tend to be a bit heavier, but with more focus on high-end performance.

This varies across their product lines of course, but I think it's fair to say both are strong contenders for good consumer VR products, albeit with different primary focuses.
