I started playing here in Japan, so those academy programs, RCM etc are not used here. I only learned about the Faber and Alfred books after I'd been playing a few years, so I've never used those either.
My piano teacher is part of Kawai's music school, and I started out using their texts for their classical curriculum. It was really good in the beginning, but now we don't follow their set curriculum anymore because it seems limiting.
Instead, I choose my own pieces, go back and forth between classical and non. For classical pieces, I either buy by the piece or use a graded collection that I have that has all the standard piano compositions.
I do Hanon and Czerny, and have just recently returned to doing some Bach as well (really liking that, after a few years of no-Bach, it's really great now)
For non-classical, (solo piano music, modern music, whatever you want to call it, like George Winston, Ryuuichi Sakamoto, Joe Hisaishi) I tend to hear music I like and then search high and low till I can find an arrangement that's closest to the original (and then it's too hard and takes forever to get worked up!
