Depends on what your needs are and where your channel is at. Just make sure you do your research before joining a Network, we would rather have people in Freedom! that want to be here and are benefiting than people that aren't happy.
One of the strong features of Freedom is the community aspect and the awesome forums (I may be a little biased there....)
Variable revenue share is also something that is a big plus. If your channel grows larger your revenue reflects that. A lot of people think Curse have the best share for larger channels with 90%, but you can get 95% if your channel is big enough with Freedom! Which mean you are giving 50% less earnings than a 90% share.
Main thing is go with whatever helps grow your channel, also don't join a network with a lock in contract...
