Indian undergrad offer decision: BB Ops or Boutique strategy consulting?

Hey, I'm a fresher. Just graduated undergrad from a pretty top 15 commerce college in India. I have two offers in hand: the Full-Time Operations Analyst Program @ JP Morgan AND the role of Business Analyst at a Boutique Strategy/Management Consulting firm with the CEO being an ex-Senior Partner @ Bain, and a few of the top team being from MBB. Both roles are offered at their Bangalore offices. I'm also planning on doing an MBA 3-4 years down the lane. Would love your opinion on which role is better. I'm aiming to grow more into strategy but is losing BB's brand name going to set me back?

Would love to hear your responses, even better if it's detailed. Thank You! :)
