• GWTP and GWT are for structured web applications;• Web apps become easily testable;• Good tooling;• GWT optimize the JS outputted code;• GWTP MVP makes it easy to work in team and to modularize

content;• Same code base for mobile web application; • It’s the best way to write enterprise web applications.

• It’s not for Hello world web application;• It’s not for small web pages;• It’s not for functional languages fan (who wants to work with

fan boys anyway);• PS: I really enjoy RAD with Python or Ruby.
