Snuffle, I don't think that a blanket statement about ALL big horns is valid. As TubaTinker referred to them, some are wonderful "amplifiers." You referred to age in your inquiry; Arnold Jacobs labeled some large tubas such as the venerable CSO York(s) as an "old man's horn."
There are some 6/4 tubas, such as the Neptune that I have on loan, which play every part of the range with no more need for air support than a smaller horn. In fact, both the low Db (all 5 valves) and the notes above the staff speak very easily. There are other factors besides air requirements that make playing the Neptune a challenge (intonation on certain notes, slurring on a rotary specimen), but those are separate issues.
OTOH, there are some big horns that require a completely different approach when supplying them with air. The huge 6/4 Rudy Meinl BBb will not respond if you attempt to "force" sound from it. You must use slow, thick, warm air. Now that's a horn that has some fascinating positive attributes, but nimbleness is generally not the first adjective that I'd use to describe that monster.
To answer your question directly, I
really enjoy playing the 6/4 Neptune in orchestra. Its broad, stage-filling (not just with volume, but with "presence"), orchestra-blanketing/supporting (NOT "destroying") sound is the epitome of what a 6/4 contrabass tuba should do for music written after 1870 or so (as opposed to parts originally written for ophicleide or serpent for which one would use the original instrument or a bass tuba).
OTOH, I brought the Neptune to rehearsal of my 11-piece brass choir. While it is possible to play that big horn softly, its overall tone quality did not blend as well in what is still essentially a chamber setting as my 4/4 Nirschl CC. Now I use the 4/4 CC in the brass choir for most pieces and my 983 Eb tuba for lighter, higher pieces.
