UCLA MCDB VS. MIMG

Hi! My current major is MIMG but I’m considering switching to MCDB because I’m more interested in the class subjects. Im a fourth year student and have taken several upper division MIMG and MCDB courses. From what I’ve noticed, the discussion section for MCDB courses are more interactive by discussing journal articles on a weekly basis while MIMG courses only review lecture topics. What other differences are there between MCDB and MIMG? I’d appreciate any input you can provide. Thank you!
