In the US, in the music depts of the colleges and universities, yes, there are worn-out duds, but there are also many excellent professors, both in the teaching of music and the teaching of music teachers.
Where are they? Well, you have to find them, of course.
In my admittedly incomplete experience, the good ones are excited about what they do, and the music school is exciting and enthusiastic about what they are doing, and it shows. They are eager, they can't wait, to share what they know, what they've learned, what's new, what works.
