Project with both Arduino C/C++ and python scripts. which is best: Pycharm vs CLion?

I have  a project that combines both C/C++ (in an Arduino) and Python scripts.

This project is going to start off simple and, if successful, will likely get much more complicated:

• multiple microcontrollers STM32 and a couple of others on the C/C++ side. Maybe Raspberry Pi?
• multi-platform on the Python side i.e. initially Ubuntu, then macOS and Windows

Which tool do you recommend: PyCharm or CLion?

If you choose Clion, Cmake based or Makefile based?
