Both do look amazingly alike. Swapnut however connects you to Swapnut users where the other programs connect you to all gnutella applications. Since Swapnut forces its users to share files, I think that is where the previous post about being able to download better comes in. That and the fact that it acts like Kazaa by shrinking to the system tray instead of closing all the way down, keeping peoples PC's connected to the network so others can download more. My 2 cents. You can't turn off uploads either, so your shared folder files are shared whether you want to or not.
