We don't have a comparison chart for that software, but we do have a description of the UltimateWB features at https://www.ultimatewb.com/features , and online Resources you can browse (under the "Resources" tab on ultimatewb.com), including a user manual and video tutorials. You can also play around with the demos at https://www.ultimatewb.com/demolinks .
UltimateWB is very flexible software. You can check out a sample of the different websites built with it at https://www.ultimatewb.com/showcase .
As it seems like you are interested in building a social networking website, you would want UltimateWB Full, which currently is a one-time fee of $249, and includes 1 year free of software updates.
