The first week, I bought every flavour to try them out, see which one's I liked. Your cdc should let you swap if you end up with one's that you don't.
Personally, the only soup I have is the oriental chilli, though I have had the other's in the past, I've gone off them as time has gone on and it's the only one I've continued to like. The shakes, I like pretty much all of them, not really into the chocolate one's, but I'm not a big chocolate fan anyway
