I voted None, but there is an explanation due.
While I prefer to have as many options as possible, PC choices all depend upon the campaign and the strictures defining its limits- if the DM says Core only, and I want to play in his campaign, I play Core only. My current main group plays 3.0 with class splatbooks, so I'm almost there right now.
But even in a wide open campaign, its not unusual for me to play somthing completely (or nearly completely) core.
