As you can see I ended up going with the "Pull" knob. I did go back and forth, precisely for the reasons those who suggested the crystal pull stated--it would give it a bit of shine and a touch of elegance. I loved Stacey Anne from Rendition Road's analogy of the table looking like a well-worn tuxedo with stories to tell!
But in the end I decided to go with the majority's choice of the "Pull" knob. I like the touch of whimsy, and its graphic quality.
I'm really happy with how it turned out.
