$begingroup$ I'd suggest this question would go better over on gamedev.SE rather than here; that said, if you're trying to do rigid-body physics, then quaternions are as simple as possible; Euler angles will turn out to be much messier on several fronts. Angular velocities are effectively a degenerate quaternion, with 0 w component (i.e., a vector); …

You got these velocities from a gyroscope, for example. It is as easy as summing them up over time. Of course, the mathematical background is a bit more complicated but that is the principle. And the other way around is possible too. From the different poses we could get the angular velocities between them (given a time period.)
