Prestige/Exit Opps Question - McKinsey Research Analyst Internship

Hey guys, this is my first post on this forum, thanks for checking it out and giving me some feedback.

I go to a non-target outside of the US, and I scored a summer internship at McKinsey as a research analyst intern. This would be the last internship I do prior to graduating in 2021, and they made it clear that they will extend a FT offer assuming you don't fuck up. I think I'd like to end up in the Business Analyst track instead of the Research Analyst track, preferably at an MBB when I graduate, but I suppose I'd understand more about the role this summer and see what appeals to me.

I want to ask what the perception is of someone who does a summer research internship at McKinsey, is it still considered prestigious and viewed well for full-time recruiting? I did the PST, passed multiple case interviews, etc etc. It wasn't easy in my opinion but I don't know how tough recruiting is for BA internships.

Would this experience be favorably viewed when trying to recruit into MBB, Deloitte, PwC, Accenture, and boutiques like Delta Partners, etc? And do you think this experience would be viewed more favorably than an advisory internship in a Big4?

I appreciate your taking the time to read this, and for any feedback or advice you might have for me. This may all end up being pointless as corona has caused the start date to be deferred, and I hope the internship still happens haha. That being said, I'm frantically applying to a lot of places for backup and just wanted to get an idea of how my current opportunity might help me in FT recruiting!
