I've been using Vim since 200x (i think 2007, but not sure), some time even as my main editor, but this is simple not true at all.

I've been trying the "built your own IDE from the editor" approach using Sublime, VSCode, and several other editors, but it doesn't work as good as good IDE. Especially the I in the IDE is important. And also that it actually really works and is integrated by someone else. I can't even remember how many times I've got broken things in VSCode, for example when I was using rope (refactoring library) or MS plugins for code analysis.

PyCharm has a superior understanding of the code, which allows you to do refactoring and other things effectively. What convinced me to use it was when I've seen other people use highlevel features like "take this piece of code, move it into own method and set theese default parameters" without even thinking, in split second decisions. I've read Effective PyCharm and kinda decided, that I don't have enough time to try to make my own IDE from things that will never get the integration to the level PyCharm already has. It was a pain (it took me something like two weeks just to map all the keys and set the defaults), but it made me much more effective.
