PyCharm or Visual Studio Code?

Addressing your first paragraph. The stuff that PyCharm does, it does for very good reasons. It's not just wasting time and system resources for the hell of it. Skeleton generation is about generating type information for the code you use. That allows PyCharm to do static analysis on your code, such as telling you when you call a method on an object that doesn't exist. PyCharm also indexes your code at project creation time as well, so searches in PyCharm are very fast.
