pixhawk for my drone

There is public holiday in Poland today and I spent some time to review open source based autopilot boards. This is probably one of the last my investment in drone parts for a long time. I have chosen Pixhawk from Radiolink company:

After reviewing many forums I’m still confused if there is any good board on market right different than old 3D Robotics Pixhawk.
Regarding Radiolink I don’t know now if this is good or bad choice I will understand it probably next year but now I can focus on 3D  printing part and forget for a while about flying controller part.
