I think it is a personal preference, I love the Veritas Press Cards, how you can hang pegs on the learning, and have lots of books of choice to choose to go along with it.
I love SOTW 2, however, it does not have enought "christian" "Reformation" stuff for me, but it is still good.
I love TOG it is great, but very expensive to get all the books, and they weren't in my library.
But I would say they are all great. It would definately be a personal preference on how you want it taught to your children. GOd bless, nancyt.
