Basically, there is no difference in SEO between those 2 tlds (I also have 2 .co's and they are ranking just as fast as .com's) but the .com extension currently is much easier to remember as the .co hasnt been around for so long. What you can do is start building the website on your .co tld and then redirect the .com domain to your .co domain so that you dont lose potential visitors.
But still, if I were you, I would wait for the .com domain to be transferred :) in the meantime you can start getting articles written, find appropriate images, keyword research etc. until the .com is transferred, so you wont lose time :)
