That's a fair question! I would say music choice has more to do with whether one enjoys or dislikes the overall sound signature of an IEM. As for sources, I couldn't say. Some people seem to hear huge differences, others don't. I'm in the latter. That in mind, it's probably more to do with a difference of hearing.
Particularly of importance is what we (as individuals) perceive as neutral. I believe you’ve owned the Moondrop B2. For the sake of argument, then, let’s say that Person A considered that neutral. Then let’s say Person B considered the B2 Dusk, which has more bass and a less upper-midrange oriented tuning, as neutral. For Person A, the Bravado would sound incredibly bassy and distant. But for Person B, who perceived a more bassy and less upper-midrange oriented IEM as neutral from the outset, these differences would not be as pronounced! You can see that if you have a baseline for what you perceive as neutral, it also helps considerably in answering what accounts for these differences.
An even simpler explanation for these differences might be how we define what we're hearing. You noted that the Bravado does sound recessed to you. Your recessed, then, might be my interpretation of distant, as they more or less mean something similar.
