Of the major keys, I like Eb major the best. The greatest symphony ever written, was written in Eb major.
Now there's a tough one - "the greatest symphony ever written"! But let's assume that it was indeed written in that key; was it composed by Elgar, Mahler, Schmidt, Beethoven, Sibelius or whom? (presumably not Shostakovich, for his ninth might be his "ninth" but it's hardly his very best!)...
As to the subject itself, I might just have a think about that should I ever feel impelled to write one...
