PC is more flexible, especially regarding Multimonitor Setup, Joystick/Yoke, Rudder Pedals and other devices.
PC is fragmented hardware, so more complex in combination of different vendors for components. Did they optimize FS2020 for Intel or AMD, or do both perform and behave nicely?
IIRC the biggest difference compared to the old versions is that live streaming of the scnenery. A year ago or so it was stated that you need at least 50Mbit Internet to avoid preloading, and for full Quality and full features like 100MBit and above. I don't know if that's true at the end. Then also make sure your storage can cache all of it fast and reliable (SSD still have issues with permanent overwrite operations?).
