You're really looking for patterns on the staff rather than the exact pedantic notes that are present in the notation.
Me? Still learn best by ear. Unfortunately this is also the slowest method....
There is also the problem that human memory has limitations, and if I stop playing something, I will forget it after a couple of weeks, so again musical notation is very helpful.

Exactly. Playing the exact tune becomes boring after a while; music is a fun creative exercise for me, so the notes and chords are a general direction, not a precise roadmap. If I wanted a perfect interpretation, I'd listen to the recorded piece instead of play it.
