UK based here.
I was in scouts, and my little minion is now also in the lower levels.
I personally think it fills a critical need for a lot of kids. Schools are locked hard into the national curriculum, and don't have time for the more character and skill building events. Scouts cover this nicely.
Regarding my local group. So far, my experience has been excellent. The kids adore it and they are doing a lot of fun learning. E.g. recently they did fire lighting. Learning to use matches, and basic fire safety around candles etc is an important skill. Learning as a group also means they learn from each other's (minor) mistakes.
The group is also mixed gender. While it's mostly boys, there are enough girls that it's not intimidating for either gender. Its activities are "boy focused", so most of the girls are of the tomboy mindset.
There are a few religious aspects attached to it. The pledge/promise mentions God. In practice it's mostly non religious. What religious elements there are, are quite inoffensive. I've also noted that the older groups have a choice of pledge, including a non-religious/atheistic option.
Also, regarding some of the scandals, the UK government now has quite rigorous procedures in place to protect children. Enhanced DBS checks are required for adults in a supervisor roll. While not perfect, these checks stop someone jumping from area to area to avoid their past acts. Parents, teachers and other helpers are also a lot hotter on spotting minor discrepancies before they can escalate. It's just done calmly and quietly, to avoid accidental witch hunts.
Basically, my minion loves scouts, and I am completely comfortable with them attending.
