Hello!
Hopefully others will continue to respond with their feedback, but as tunde michael wrote, students often use one or both. Of course, we are most familiar with Kaplan notes with which many, many students have succeeded. Dr. Goljan's notes are quite popular also, and we can attest to their quality as Dr. Goljan used to teach for Kaplan!
We recommend not using too many resources as it could slow down your prep.
