Story of the World History Encyclopedia...which one?

[Mama Geek]

I am planning to do the 4 year cycle throughout and just getting started this year.  What history encyclopedia would you buy with that in mind?  I know there is Kingfisher and I know there is Osbourne.  Dd's reading level is already pretty high, she is reading books like Black Stallion right now.

I used the Kingfisher, and that way was able to transition to logic stage outlining work with it, without buying something new
