I think there are several issues at play here.
Firstly, it is not easy at all to separate our sense of what is loud from our sense of the timbre of the instrument. A trombone may be ear-splittingly loud, but most would readily agree that a tuba sound is
bigger. So, what do we mean when we use terms like "bigger" and "louder"?
For me, "louder" applies when I want the instrument to sound like an individual voice, well-distinguished within the ensemble sound. "Bigger" applies when I want the tuba to enlarge the sound of the whole ensemble. It takes a different tone color as much as the ability to swing the needle on an SPL meter.
I've also noticed that tubas often described as "dark" often have sound with less upper harmonic content, resulting in what to me is a woofy sound. This does not promote clarity or a sense of presence. The good players on such instruments distinguish themselves by the ability to add harmonic content to the sound of the instrument so that the power has something to work with tonally (think Bobo playing a Miraphone). Those upper harmonics are what carries the sound to the back row, it seems to me. It was actually an oboe player who first described that concept to me. One of the things I like the most about my Holton is that it has a colorful sound with lots of obvious but well-blended upper harmonic content. To me, that is the distinguishing characteristic of the best big tubas, and I played a lot of them before I found it in an instrument I could afford.
For music such as transcriptions of Berlioz, that individual high tuba voice is important for the music originally in the tuba part, because Berlioz mostly used the tuba as a soloistic color instrument. The transcribed bass parts, however, must provide the foundation. That, to me, is the main reason to use both a BAT and an F tuba in the tuba section for music like that.
My ideal horn for band is the Holton. It has the upper harmonic content to carry the sound to the back row, but still the breadth of sound to enlarge the whole ensemble rather than to pierce through as an individual voice. The tuba sound is definitely present, but not dominating, even when played loudly. I think this expands the tonal palette of the band, rather than homogenize it further. I also think it's why early bands often used sousaphones or big tubas the size of sousaphones.
Thinking from another perspective, I once use my Yamaha 621 F when playing a band transcription of
The Damnation of Faust. My lips were flapping out the bell because of how loudly I was trying to play, yet the conductor kept asking for more, claiming the sound was not getting past the front edge of the stage. I had two choices: I could get a bigger F tuba or a shallower mouthpiece and go trombone-like. I opted for the former, and that's when I bought the B&S Symphonie. It is much, much easier to hear amid the general band tutti, and much easier to play such that it can be heard, without having to resort to a piercing sound. But it still produces an F-tuba sound--an individual voice distinguishable within the ensemble rather than making the ensemble itself sound larger.
