Picking LOR writers based on position

Hi all, I am picking between two options for one of my LOR writers (for deferred MBA admissions at HBS, GSB, etc.) and my choice boils down to one of two people I worked with this summer at MBB. I can either pick pick between an analyst I befriended with who would write an amazing rec, or a partner who I worked with the entire summer but is probably too busy to write a letter that’s as good (the partner still worked directly with me the entire summer and would have great anecdotes, I just don't know if they'd be able to put the same amount of effort into writing the letter).

On face value, the LOR from the first individual would be stronger - the only differentiator is the title of the second individual. However, from reading over the questions for each LOR on clearadmit.com, it appears that the review system never asks for title/position. Am I right in then assuming that this distinction doesn’t matter, or will the adcom reviewers look up the reviewer to check their position/tenure at the firm?

It’s also worth noting that since I was an intern, the analyst (despite only being a year out of college) was more or less a direct supervisor and is willing to state that on the form, as would the partner.
