Citadel Securities vs Citadel GQS SWE internship

So I was lucky enough to get SWE internship offers from Citadel Securities and Citadel GQS, and honestly, I have no idea how to choose between them. Any thoughts or experiences would be super appreciated.

Here’s what I’m mainly thinking about:

1. Job security: Which one has a better chance of a return offer / less likely to do layoffs?
2. Long-term money: They pay the same for internships, but I’m not sure how comp compares full-time down the line.
3. Culture: I’m expecting long hours at both. I don't mind it, but I care more about who I’d be working with and what the culture’s actually like (e.g. are SWEs treated way worse than QRs?).
4. Career growth: Which one gives better long-term opportunities and learning potential?
