Well, yeah. But that's not the primary reason. Recall that "CV"
stands for "Constant Velocity"
A u-joint has a funky kind of motion as it rotates...the ends of the
yokes go in and out, and so the speed changes slightly as it
rotates. The CV joint minimizes this. A CV joint also eliminates
the possible notchiness at extreme angles of input relative to output.
Some interesting mathematics

And some pretty pictures here
