SQLGate proved to be a very easy and powerful tool. First of all, it's fast! The quick data analysis really did wonders for speeding up my work, and the functions are both intuitive and easy to pick up. It includes a PL/SQL editor and debugger that helps catch any mistakes which comes in handy. Better yet, there are plenty of autcomplete and template functions that really help speed things up. There are also a few options for skin color, so you can customize the window with a color that suits you. I really like the dark skin.
