This project is much more lightweight. three20 certainly has more features, but it is large and relatively complicated compared to this. IMO, this project has a much more narrow scope. And that is a good thing when I don't need all the three20 features (the majority of the time). For all the good three20 does it can be cumbersome to integrate into a large project, and it's documentation is less than stellar.
