When we used to ask this in ps, most of my class said "recess". That was kind of depressing, though I kind of expected it, at least from the boys (sorry to sound stereotypical, but it was about the only time they got to move! 
). I asked my oldest ds (who's doing RTR) this question, and he answered "reading". In ps, that would have meant the subject of reading, but when I asked my ds what he meant he said, "Well, all of the books we get to read. You know, like "Peril and Peace", "Exploring Astronomy", "Mystery of the Silver Coins", that "Boyhood book", my DITHOR book - you know mom, READING!" I had to laugh. I think he touched on almost every subject of school. I guess this is a thumbs up for the living books approach. My middle ds always just answers with the last thing he did. It seems to be whatever's fresh in his mind. So I asked him after we finished math, and he said, "I love math!" But then after I read "Understood Betsy" to him, he said, "Oh no, I have to change my answer, this is my favorite!" This continued throughout the day.
Maybe this is one of those questions older dc can answer better, but what about your kids, what's their favorite part of HOD? In Christ,
