Preference between Mara Pratt's American history stories and Geurber's Story of the 13 Col

I am planning to cover the Module 5 time period next year and will probably loosely follow the SCM handbook in order to do this. However, I already have both of the above US History spines – Mara Pratt’s American history stories and Geurber’s Story of the 13 Colonies. I would rather use something I already have rather than purchase the new US History Spine that SCM published (although I’m sure it’s lovely too! – just a matter of trying to make the most of my budget.) I have read through fairly significant portions of both of them and personally have found both engaging, and find they read sort of similarly as well. So…I am having a hard time deciding which one to use. Has anyone here used either of these and found that you or your children had a preference for one or the other? And at what ages? I will be using whatever I decide primarily with a 7 year old (although I have two preschoolers as well who may listen in from time to time.)

Thanks for any feedback!
