Honestly...
Stick with .com
I recommend reviewing the sales of domain names as a whole, and see which tld performs better? The truth is - if your a company looking to purchase a domain name to build a site or platform on, what TLD are you going to choose?
.com - without a doubt. I wouldnt build anything on any other TLD. In the public conscious there is .com and everything else. Learn about what makes a domain valueable, then go after a few domains in teh aftermarket or the drop catchers. Good luck!
