Go MRSM lah, because you can wear polo shirt to class, more comfy than kemeja...Plus got 'Activity Week', one week without classes = pure win. Every semester you can get Anugerah Pengetua, pretty much like Dean's List so you can have the university feeling there

I've been in both SBP and MRSM, and I'd say both got its advantages and disadvantages although it doesn't really matter once you enter university.
