I think the general consensus is that bigger girls are less sought after. I wouldn't "go after them". I'm not sure what you mean by your question though. Do you mean to say that is it wrong? In which case, no. Better? That's up to you really. Difference? Yeah! Size, but that's all.
Basically, we all have our *ahem* preferences. By today's standards, it's pretty ok though. Go get 'em, mate.
