Which is most important for launch?

We all know that having a great product is essential. In my experience, my product wasn't quite ready for our first launch—it lagged behind competitors in certain areas. However, with a little support from the #buildinpublic community on Twitter, we secured the #10 spot with 150 upvotes! Now, I'm launching the new version on November 29th. What matters more? Community support on social or improving the product? My focus is divided, but I think choosing one will yield better results.
