Anyone Using TextMate, Other Editor Recommendations?

[Kalimba]

I'm just wondering if anyone else here is using a code editor other than the one Xcode provides. I've read good things about TextMate, so I'll probably be looking in it, but was hoping someone had first-hand experience with a "better" editor.

I've gotten used to the Xcode editor, but I haven't found a way to do some of the key things I'm used to in other environments. Specifically, I've found that it's extremely difficult to switch amongst my "open" files in Xcode using only keyboard commands. I've learned the keystroke for switch between the .h and .m file, and I use it all of the time. But selecting another file involves using the mouse to select from the recent files history or the project file tree.

Perhaps like many coders, I'm usually working on a small number of files simultaneously, and the ability to select one of these "open" files via keystroke is an invaluable time saver. In many other editors, there is the ability to display a list of open files in a dialog boa and select one via keyboard.

So... has anyone found a good editor that might fit the bill?
