Hi,
For drone application, we recommend BMI088. The BMI088 is unique in the class of high-performance IMUs used in harsh environments such as those ones in drones and robotics applications. Apart from its high vibration robustness, the excellent temperature stability of BMI088 helps reducing design efforts and costs on a system level.
BNO055 is smart sensor with BSX algo build in, you could directly get Euler angle and Quaternion.
Best regards.
