I agree that you should choose a career path that makes you happy and that you are excited about. Going the MBB route will do 3 things:
1) Give you more exposure: At an MBB firm, you will work on a diverse set of projects that involve different types of problems in different industries, thus broadening your exposure
2) Accelerate your learning: I always used to tell candidates that you learn in "dog years" because you truly do learn at a much faster pace in consulting than in almost any other field
3) Receive a great deal of mentorship: Mentorship at the MBB firms is a core value and is a way to quickly understand areas where you need to work on to get better. You don't usually receive that in other settings
Hope that helps!
