What's the best IDE?

Recently I've had some problems with PythonWin when I switched to
Py2.5, tooka long hiatus, and came back. So now I'm without my god sent
helper, and I'm looking for a cool replacement, or some advocation to
reinstall/setup PyWin. But the Python website's list is irrefutably
long. It would take a month or two to test all of those products. So
I'm looking for experienced advocates.

What's your favorite IDE?
What do you like about it?
It would be fine for a begginer, right?
