Hello @Linmaackerman welcome to the community,

Explain your usecase in detail. Otherwise is like asking should I buy a Porsche or a Ferrary?

I am building 92kg Quadcopter drone. I want it to high stability and low vibration in air. It’s my first time building that big drone

Both are very good flight controllers for that vehicle.

How are you planning to configure that vehicle?

likely they are both open hardware.

Here is a comment that may be useful to you.

Uhh, are you not considering motor redundancy? What is your estimated propeller size?
