personal opinion. ACCP book is painful and damn near unreadable. I'm not much of one to sit through lecture anymore and only made it through ~1/2 of in person courses, they're good but there wasn't enough coffee available to keep me sitting whole time. I used combination of seek (latest 2 sets) and the chest board review videos, I listened to the audio.
SCCM material was OK. then again, I did the online version so I was not participating in the questions that they were giving to the audience and sometimes I did not know if my answer was correct. But between that and the questions from CHEST, it was fine
I can't speak for the ABIM exam, but I felt that the SCCM review course (did mine through on-demand, rather than going to Chicago), plus Chest SEEK and the SCCM question banks were more than adequate for the ABA exam.
