SPE will be reviewed by the same person for the next PyCon against WingIDE, Komodo and Pydev. Maybe you say which features you want to give a better answer. I don't know about WingIDE but I do know about SPE ;-)
Things which we want to have ready for the review: - integrated debugger (now WinPdb runs external) - configurable keyboard shortcuts - configurable color schemes - realtime syntax error underling (already implemented, wait for 0.8.1.c) - ... Well, much more features are implemented almost daily as more people start also contributing. Stani -- http://pythonide.stani.be -- http://mail.python.org/mailman/listinfo/python-list
