Detailed
Subway will cut down on the raw number of lines of code you need to write. It will automatically generate a skeleton of your web application that will instantly run. You may then modify and add to this site as you see fit. Subway also provides all of the standard tools you need to create commercial-quality web applications: built-in, easy-to-use form handling and validation, separation of code and HTML (MVC), multi-user scalability, strong sessions support, and most importantly relational database support. Using a database in Subway is a snap, just take a look at the NoteBoard example that comes with Subway to see how easy it is.
With most other tools, you'll end up writing jumbled up pages of code, sometimes mixed with HTML. Or worse, you'll be working against an overengineered, complex framework with a steep learning curve that gets in your way. Subway keeps the mess of writing web applications clean and easy. You're using an elegant programming langauge, Python, with an elegant web framework. Subway is also very modular: you can expand your site larger and larger, and it will stay organized. You can also painlessly add integration with other Python-based technologies, too.
