Yes, I agree HL isn't very exciting, but pedagogically it's rather better than most of the alternatives. I just lend my (by now rather battered) copies out, at the appropraite stage in MFPA ( not the Primer, which for some reason I've never got on with). I find the material in MFPA very attractive, and appealing to most of the age group, with the duets, and the CDs, whereas Alfred I remember thinking to be quite banal. I like the way MFPA uses fingers 2,3 and 4 for some time, before introducing the thumb. A typical 6-7-year-old's natural hand span is usually smaller than a 5th, and it will lead to tension if they are stuck in this postion too much, too soon. Imagine what is your own widest stretch - maybe a 9th or 10th - and then imagine playing all your repertoire stuck in this position, especially if you are new to the piano. Irina Gorin is especially passionate on this subject, and her books, Tales of a Musical Journey, completely avoid 5-finger positions, and also start with using fingers 2,3,4 on CDE as a default, rather than the traditional ( in this country) 1,2,3.

Hope that helps. I now teach beginners in a completely different way than when I started. I wish all this wonderful material had been available then!
