My philosophy is that CG should be CG and everyone should use the same one, with the same systems and points.
If your setting has need of special positions, rare concepts or abilities, etc etc, you can address those things by making some kind of tradeoff in CG. Pay some points, get access to whatever thing.
'Some people just get more XP/all the cool toys/whatever because they're special' (which nearly always means they're staff's buddies or just got to the game first) is a fundamentally retarded idea and everyone who supports it (so, I dunno, most people who make WoD games) is wrong and should feel bad. The end.
