Mark, I too am a lover of JS Bach, and your passion is laudable. In all of the movies and television shows and videos I have seen, the most moving musical performance I remember is Yo Yo Ma's recital of the Suite No 1 for Cello in an episode of The West Wing. After first hearing it, I acquired every one of Ma's performances of Bach I could find, and I still remember the episode vividly to this day. No other composer's music could have had similar impact, IMO.
On the other hand, if Beethoven wrote nothing else except the 32 piano sonatas we'd still be having a debate, just based on that one body of work. And, as you, know, Beethoven produced a lot of other work that's pure genius. You may dismiss the debate, but, frankly, I don't stand in awe of any of Bach's music the way I do those 32 works. As a massive body of work Bach may be the pinnacle, but the piano sonatas are, what a friend of mine used to call, my desert island music. (The music I would take with me to be marooned on a desert island, if I could have no other.) It wouldn't be Bach. Preference is always debatable.
