As with Rja, I've never totally warmed to his symphonies. It may be because I believe Mozart loved the solo voice (the melody) and understood the push pull/give take of that voice better than he did the symphonic voice.
In many of his fist movements he gives a superficial nod to the crucial development section. Listen to a Beethoven 1st movement development and then compare it to a Mozart development and you may see what I mean. My wife and I have had this discussion and she disagrees with me. She doesn't disagree that a Beethoven development is more interesting, she hears Moazart's symphonic developments as being perfectly balanced to his overall symphonic architecture while I hear them as superficial given the amount of amazing musical material that preceded said development. Bear in mind I am not saying his symphonies are not works of genius...Anyway, interesting food for thought.
