Well, I have all boys and have gradually gotten all of the books (even the girl interest ones) just because I think they are all so good. This is helping me slowly build my own personal home library. The classic set requires a more seasoned reader than either the boy interest or girl interest books do. With my oldest, we did the classic set, and then I got the boy interest set the next year for him to read on his own. After that, I got the girl set, as I wanted those on hand as well. With my middle ds,I did the boy interest set for Beyond's Storytime with him. This may just be me, but I was excited to read different books the second time around doing Beyond. Not that I didn't love the classics - just that I enjoyed reading different books with my middle ds as it was just a fun change. So, I guess if I were you, I'd get either the classic set or girl interest set (or both), depending on how your dd listens to books being read aloud. Then, when your ds reaches the Beyond age, you could do the Boy Interest set (or the classic if you either didn't do that with dd ,or if you didn't mind rereading them).
As far as LHTH, it does not have read-alouds, but you could easily have your little honey listen in on Beyond's books if he's able. My middle ds did that when I was reading to my oldest ds for Beyond.

These are just a few ideas I had, but just know you can't really go wrong with picking a Storytime set - all 3 are outstanding. I wish I'd read more books such as these when I was that age - but, I guess that just makes me enjoy these all the more.
In Christ,
