The reason I haven't responded in this thread before(I think?) is because I worried it might be rude to say....none of them.
Intended or not, I think it's actually some pretty valuable feedback that Larian could observe, that a thread of this topic found the Vast Majority of responders wrote in to say "None of them" and then give their reasons why, to various degrees. That in itself is telling data.
As an amusing aside, a decent portion of those few who responded to the thread with an actual origin character preference listed their reason for doing so to be that it would be a way of having the character in the party mechanically, without having to deal with or put up with having the character in the party... which is, it must be said, not a point in the origin system's favour either...
