Go for what interests you. If you wanna go into IT sector, take up BCA. If you're interested in banking sector, take up BCom. Decide well !!

Well, any of the two will be good. You'll have to complete MBA to get what you wnat.

Which field interests you? Banking sector or management sector?
If banking, go for BCom and then you can do MCom or LLB or CA or CMA or CFA.
If management, take up BBA and then do MBA from a good college and get highly paid.
BBA can take you to MBA only whereas BCom has lots of options as you see above.
1 more thing: After doing BBA or BCom, you become eligible for sitting in compititive exams like IBPS, UPSC, SBI-PO, SBI-Clerk and other bank and railway exams to get a job.

Dear Rishabh,
Both are best, if person pursued is passionate and skilled.
We can never compare two streams, you need to choose the one you like the most.
That is the only way you can be happy & successful in your career line.
Hope it was of help,
