Hmmm. My son likes both, but definitely prefers LofF to MM. I purchased the first LofF (I think decimals, but maybe it was percents) for him when he was crying over his math nearly ever day in 2nd grade math. I tired to be formal and told him he had to do the problems at the end of each chapter in order to move on. Well, that lasted all of about 3 weeks, because shortly after he tested up 2 years in math! At that point I let him read decimals and percents just for fun!
Fast forward to this year. He read the algebra one for fun and never did any of the questions. But he loved it and begged me for the higher level math ones (geo. , trig and calculus). Teasingly I told him I couldn't buy them for him because his brain would "explode." At that point, I purchased a number of the MM books (I currently have the last LofF on order and will let him read them this summer, he is dying to find out what happens to Fred, but in some ways, I didn't want him to get ahead of himself). He has read some of the MM books, but not with the same passion - he likes them, but he loves LofF.
So, why did he like the MM books, but def. not as much as LofF. I have read the first 3 LofF books and I laughed the entire time, the MM books seem to have a different type of humor. I think it may just depend on personality. LofF are more linear, and I think my DS and I both are fairly linear thinkers. Maybe that is why?
Anyway, both series are fun. Maybe just pick up one of each used and see which your child prefers?
