My mom has started several businesses (short attention span!) and so I've tried Unbounce, Squarespace, GoDaddy pages, various WordPress hosts (HostGator and BlueHost and others)...

This one looks like it's going for the Squarespace/Wix market.

I think what matters the most in that space is getting out of the box with a very nice looking template - Squarespace excels there! (heck, their current landing page says "Make it beautiful"). And they have a nice logo creator.

This one doesn't seem to have that much design in it. On the plus side, it does say "No signup to try out" (that's a huge plus, hope spammers don't abuse it) and "simplest", which is what I expect your target audience to like.

Edit: on the builder, I think you should emphasize starter templates more.
