Chuck Klosterman had a good Led Zeppelin hypothetical of if you would rather be Plant or Page since they both seem to have polar opposites with their approach to Zeppelin:
Plant seems to have little to no interest in being Zeppelin and wants to do like bluegrass and folk shit with Allison Kraus etc.
Page only seems to want to do Zeppelin and the glory days and has little interest in anything else.
