Choosing Between Internships: Strategy intern @ branding/marketing tech startup VS Business Development intern @ Big4

I'm a rising junior aiming for strategy/management consulting and right now struggling to choose between 2 internships.

Both are off-cycle, so I'll have to take a gap semester.

In theory, which of these would look better on my resume? Which of these would help my networking more? Which of these might be more engaging?

1. Strategy & Finance Intern at branding/marketing tech startup

Company focuses on using tech for marketing/branding, <200 people.

• Direct report to CFO. Great guy and has director level experience at top IBs and HFs. Top undergrad as well. 

• Mostly high level: identifying expansions and business growth opportunities, might be some modelling/budgeting work.

• Interesting topics: VR/AR, Digital marketing, Web3, Metaverse.

• Startup has already had some cool clients (and a really nice website), but still massively loses out in brand name vs Big4.

2.  Business Development Intern

One of the okay Big4s, has a strategy arm 

• Referred by connection, but the interviewers really liked me as well. Will be assigned to random partner I haven't met.

• Department goal is basically to cross-sell and "improve customer experience".

• Stakeholder management, working with a bunch of departments. Some client facing work: sitting in meetings, POSSIBLY pitching.

• Red flag? Interviewers said the role might not be what I expected, and would understand if I wanted to cut the internship short (!!!)

Thanks in advance for any ideas.
