Not really.  They have different approaches and opportunities in each organization. I'm somewhat biased in thinking the BSA is the better program, I'm sure there are girl scout leaders that think the opposite. 

Its not about power at all.  Are we somehow making girls more powerful by saying they can earn a wolf badge the same way a boy can?

If there is any power curve I guess it makes the BSA more powerful by saying, "Hey we serve everyone, bring the whole family in Monday night."
