PX4 and Ardupilot compare

Does anyone have the opportunity to take a look here?

By the way.
I think, ardupilot should also take a look every now and then to PX4.

Hello,

What is the point a looking at a px4 log ? Both autopilot are really differents so it won’t help us in anyway.

Most are looking from time to time what px4 is doing, but there codebase and goals are really differents so comparison is really hard.

Is there some body who has an overview over the differences in detail?
I would like to understand it, but first i have to learn all over the ardupilot-firmware.
