EDIT: well thinking about it, I guess it wouldn't matter, as XBMC will downgrade it automatically anyway.
Sure "best" can vary. If you only have a DD decoder than DTS is hardly the best. But the system should already know you don't support DTS via the sound settings. Is 6channel FLAC better than DTS? stuff like that. There's always trade offs and so many variations, but a good priority level is better than it just choosing track 1 all the time.
I still prefer AC3 downmixed on my box over someone else doing it and compressing it to AAC or MP3.
