I started all my kids out on Saxon. By time my first dd got to Saxon 5/4, she pleaded with me to change. She hated it. She really needed something that would immerse her in a particular topic so we switched her to R&S. My other two are doing fine with it and seem to enjoy it so I will stay with it for them for now. My only complaint is that they do not drill the multiplication facts up to 12. Not sure why but that is very easy to remedy on your own.
