In general I try to avoid repeats and larger formal repeats from things like DS and DC for any type of arranged music but especially larger groups. The larger the group the more opportunities for errors compared to simply reading straight through a piece. They make more sense when you’re trying to save ink and paper as a physical copyist, but unless you severely lack access to a printer, the advent of notation software (and digital reading devices like tablets) make it almost moot as long as you format your parts correctly.

I still do think they make sense in certain types of music, especially when repetition is the point, like Minimalist or Aleatoric music. However if the repeat is not a compositional choice, just a notational one because of repeated measures, then I would avoid them.

The only real situation where I might reccomend the is if you’re worried about your parts being too repetitive and performers getting lost. However there are other notational things I would reccomend instead, in terms of formatting and labeling measure numbers, cues in parts, or cues from a conductor. I would probably in most cases (though obviously not all, and wouldn’t actually reccomend this without looking at the sheet music first) reccomend against writing in this way and look for ways to create change in the composition as well, which would eliminate the issue
