Hands down TubeMogule Beats Heyspread based on free features.
Heyspread does offer some pretty cool features but implements a pay for credit program that requires you to buy credits to access all the features. The one feature that is cool on Heyspread is the YouTube Clone makes it fast to promote all your existing videos.
TubeMogule was quick, easy to use and free! Not to mention a real time saver!
Please note TubeMogule has a video distribution limit of 14 videos per/month for free account holders.
