Both IIM Kozhikode and SPJIMR offer an excellent curriculum in MBA that is taught by the best and most learned faculty. One of my cousins chose IIMK over SPJIMR because she was inclined toward Finance specifically. Additionally, the IIM tag helped her avail better opportunities. 

SPJIMR on the other hand has a few drawbacks that make you want to reconsider joining it. Firstly, it has a triple occupancy room system which may not be fit for everyone. Secondly, its culture is a bit restrictive focusing only on mental development.

Overall, If you are a CA or a CFA graduate with Financial Corp experience, you will be exposed to similar cultures and opportunities on both campuses. But if you are an engineer, you will get better opportunities at IIM Kozhikode.

 Ultimately, the final decision is yours to make!
