I bought SOBH right as the advanced version was released and switched right away, so my experience is limited. AFAIK, the advanced version simply compiles rules from other supplements and adds a generic spell list.
And so long as I'm confessing - ASOBH is the frame we hang our fantasy games on. Great game but we're not strict about it. We've never used the point system or adhered to the Trait restrictions. If it makes the story cooler, we do it. Things tend to balance themselves out without resorting to math or quoting rule book chapter and verse.
