I agree that, given a binary choice between euph and bari, the euph will get a lot more usage. I did buy a Chinese bari when I was switched from euph to bari in the Brass Band of Huntsville; I wanted to have my own instrument. Otherwise, I would have never considered it.
However, yesterday the Cullman Community Band played a concert including the Holst 1st Suite, and I played the original bari part
