Let's say, hypothetically, one were taking an audition for a symphony orchestra and the panel was asking for a "solo concerto of the applicant's choice." Given the choice between one well-known, often-used-and-asked-for war horse concerto and one that's more "under the radar," and also given the following:
-Both are equally well prepared, and to a high level, technically and musically
-You enjoy both pieces (roughly) equally
Which would you choose and why? I'm curious about the perspectives of auditioners and the panel behind the curtain.
And in case you're wondering, yes, I'm faced with this decision currently. Yes, I'm pretty sure I've made my choice. No, I'm not going to share quite yet...

I was on the orchestral audition circuit for a couple of years as a trombonist before I figured out that I did not want to be a full time orchestral player, but just wanted to play in an orchestra as one part of my performing career. When working with my teacher, this came up a couple of times, and inevitably, you've already answered your question.
The key statement is "You enjoy both pieces (roughly) equally."
The fact is, the panel wants you to succeed and sound your best. Doug Yeo, of the BSO (retiring), wrote on the Trombone Forum in reply #25 that they want to pick a winner. (on this page

So, enjoying both pieces "roughly" the same means there is a preference. You will perform better on the piece you absolutely enjoy playing more, giving you a better shot at winning. Matt Guilford (Bass Bone, National Symphony Orchestra) talks about making music in this post on his site:

If all things are absolutely equal (including enjoyment of the piece), then I would say go for the under the radar piece - it could make you stand out against the crowd. But, if you enjoy the war horse even a bit more, you know your choice.
