I love my SCAR 17 and the design. The size of the BCG makes it shoot like a 223 and stock folds if needed. As an all around weapon that can adapt to situations and doesnt require a huge amount of change, I think its hard to beat. If you want to get into specific needs, that is where I think you get into some of the weapons you mentioned. There are issues with it that I dont like, like the charging handle, etc., but the reliability, adaptability and value make me keep it...
