Pixhawk px4 Esc compatibility

Hi everyone, my name is Andrea, passionate about quadcopters and electronics.
I am about to start my first project with Pixhawk px4, however I was reading on different forums of some compatibility issues of px4 with many esc.
I did not found yet a final answer on the web ,i was wondering if someone could help me out.
I would like to use the px4 with 800kw motors. Could you please suggest any ESC brand with no firmware issue with px4 and also what kind of motors you would use?
Thank you very much,
