Yeah, we are in an odd situation because there are a lot less girl troops in our area, but they are gaining fast and new ones are coming online this year (and the switch-up to allow co-ed/family troops will change/improve that even more), and as a merit badge counselor, I've seen them work harder to make Eagle than the boys. Some of that maybe due to some of the girls coming into it later and so they are on a time crunch, but the majority show up prepared for whatever they are working on, and some of the boys, you have to drag it out of them. My son is that way - it's like "come on kid, it's right there in the book you are holding, at least show me that you are serious about it."
We work with a couple of troops (as merit badge counselor) and our son is in a troop and our daughter is in Cub Scouts, and all of them appear to be growing fairly well (COVID really messed things up and we lost troops and packs in the area from them not pulling in young kids during that time), and the ones with girls appear to be growing very well. It seems like the girls in both Cubs and in the troop we work with are a lot more outdoor-focused than the local Girl Scout troops.
