I'd suggest you try Cortot's 'Rational Principles for Pianoforte Technique' instead.
I would say go for Cortot's method if you want to play like Cortot. Go for Czerny if you want to play like Czerny played. Czerny could, as a teenager, already play all of his friend and teacher Beethoven's piano works by memory. Beethoven preferred him of course to play with the score, and they both lived in the days before recordings existed. But Czerny absolutely hated playing wrong notes. Cortot didn't seem to mind. I'd go for Czerny myself. He was, after all, Liszt's teacher. If Liszt could learn from Czerny, I think we all could.
