I suggest that you reserve some time and put on the 9th and close your eyes and open your ears. There is nothing better.

I have done what you suggest, many times. I love the ninth. But the AoF is a different creature altogether. It is still possibly the only musical work written centuries ago that can still honestly claim to be ahead of its time, even by today's standards. With his canons and fugues Bach composed what is probably the most intellectually rigorous music our world has known.
Bach is more of an acquired taste than say, Beethoven or Mozart. I will admit that.
