The biggest complaint I have about PyCharm is that it can use a lot of RAM which slows down the computer / IDE. I use the paid version, and have otherwise found nothing to complain about the interface, utility, and capabilities.
Indexing and skeleton building has to be improved. It takes some time even with SSD inside the machine. If one has an HDD and also wishes to use a full-fledged Anaconda, then indexing will become a nightmare.
