Both of these curricula look very nice. However, as a veteran homeschool mom, I'd choose the HOD curriculum. I like how it places the "skills" addressed in the lessons into parentheses! (I only quickly perused the eighth grade week-at-a-glance, to be honest.)
When writing subject summaries for our evaluator each spring, this would have come in really handy.
Another thought I had was that of "trying out" a used workbook from each curricula...if a friend is using either of these, perhaps you could borrow one of their books and hold a "sample" school day before you make your decision.
I used to write my own weekly sheets when the kiddos were younger. I wrote basic subjects and made photocopies for my three students, and then I'd handwrite the specifics for their respective text or workbooks. Believe it or not, this was my favorite method, since I would buy used curriculum and receive free hand-me-downs...thus creating an eclectic mix.
I hope this helps.
