I'll admit Beethoven was pretty god, to say the least: I love his symphonies from the 5th to the 9ht, the violin concert is superb, the Piano Concert #5 is magnificent!. Bach is more religious than Beethoven, which was more of a humanist (like me). In my view there's a more rational 'feeling' in Bach that, as a former student of mathematics, I appreciate very much. But between these two, in the end it's a matter of taste.
