Sorry, not trying to bust on you, but I write in all these IDEs...I still love VS.
But hey, C# is just a copy of Java, so maybe it evens out.
Having said that, I just watched the screencast[1] of Python intellisense in VS, very impressive.
Meanwhile in VS, after installing the Python plugin all of that stuff just worked the first time.
However, my assessment remains the same because now that autocomplete is finally working, it's still not as good as VS in my opinion.
1) VS shows documentation for each function in the autocomplete list. (Seen here http://i.imgur.com/wQpZZ.png ) IDEA does not.
2) VS shows type information where possible. IDEA does not.
3) VS shows the autocomplete list immediately after I type the space in "import ". With IDEA I have to hit Ctrl+Space to get the list.
4) The VS Python plugin worked with zero configuration. I had to configure an interpreter for IDEA and then wait a while for it to index everything.
I really don't like having to configure the interpreters but it's also nice when you're using project based virtual environments.
