When considering a web path scanner, the following features should be considered, in order of importance.
If you can't get it to run on your system, it's no good to you.
The larger the dictionaries that come with the scanner, the better coverage your scanning will get. Also, it should be easy to specify a custom dictionary if you want to.
Output varies, but it's important that 'found' paths are clearly indicated. It's less important, but still useful, to get some progress indication as the scan goes along.
Relatively unimportant. Web path scanning need not be a real-time affair, you can just fire it and forget about it while you do something else.
