You'll also want to learn about critical speeds. If the rotation looks jerky or jittery when it is rendered then the speed is out of sync with the frame rate of the video so you end up with Judder. It's actually a stroboscopic effect. White type against a black background actually makes the problem worse. The lower the frame rate the more pronounced the problem is and the more accurate you have to be with your speed.
You can hide small judders with motion blur, but if you want to use CC Cylinder, you'll have to use Pixel Motion Blur or CC Force Motion Blur to do that.
Spend some time with the User Guide. You'll find links on this forum, on the AE Product Page, in the AE Home Screen and it will pop up when you use Search Help in the top right corner of AE.
