Tim uses Textmate, and we use Komodo. I use it because it has VIM bindings. It also gives you autocompletion of your python code. That alone makes it superior. Gives you method declarations and docstrings as you autocomplete as well. The project stuff is good. The fuzzy find (called FastOpen in Komodo) is nearly as good as textmate. From what I’ve seen, Komodo is more project centric than Textmate. I think of Komodo as a lightweight, python-centric Eclipse verses a pretty, mac-oriented emacs like I see Textmate.
