Do visit both the sites and select the best you feel beneficial. Sir may be saying from exam point of view but once you are CA you will seldom find bookish questions in day to day life.All the real world complecated examples are waiting for you.So it is all upon you when you want to tackle them head on. Make priority and decide. If you feel during exam case study questions are just burden then leave it but prepare yourself after passing exams.
