#13 this one is the most creative, with the letters!
I love the design of #13, but not the colors.
Could you try using design #13 again but instead use colors more like #15, or #16... or even better...
My favorite colors are found in the logo's #9, #10, or #11.
Not a big fan of the quote marks in #'s 14, 15, 16, and 17.
