I think there is. Not on this site, but statistics on other sites show that there are usually more Spuffy's than Bangels. On another site I go to, the Bangels there are around 240 with the lists of Spuffy's being around 570's.
But if you mean in the show, I think there was more Spuffy than Bangel. Not romantically, but I think that she was around Spike a lot more, which contributed to the connection and histroy between the couple.
