It comes down to personal preference. I didn't personally take Econ but I spent a lot of time helping friends with it and being at some of the classes. I DID take Psych 1X03 and it was easily one of the best courses I took last year as well as the easiest 12. Joe Kim is constantly trying to improve his pedagogical methods to help his students learn better and since the lectures are all online, they are very convenient and you can watch them whenever you want. You can also pause and take notes, then re-play the lecture at your leisure. This was great for me since I had a busy schedule that semester.
In addition to that, there are weekly quizes every Friday on the past week's content. Although these were a bit annoying, when I sat down to study for the exam, I didn't even really have to study that much because I knew most of the material from the quizzes.
Anyway, I absolutely LOVED Psych 1X03, but I know some people who hated the online lecture format and the quizzes. Think about what you like and how you learn best
