The most well-known 6-axis IMU that you see a lot of its breakout in the market
The production of this chip stopped unfortunately so we can’t keep buying this chip anymore, ICM 20602 is the new replacement to the MPU 6000(also out of date)
It has the same hardware named MPU6000 with additional SPI
Reviews of this breakout board’s accuracy are generally negative, but the performance of the chip is recognized by many UAV use
Sounds like the breakout board has an uneven quality
Adafruit has pretty detailed how-to-use instruction:https://learn.adafruit.com/mpu6050-6-dof-accelerometer-and-gyro?view=all
Outweigh the performance of other chips:
...
The latest in a long line of quality Accelerometer+Gyroscope 6-DOF IMUs from ST
Has well well-documented datasheet
Also has a machine-learning core

Summary
LSM6DOSX is my favourite 6-axis IMU chip of all chips so far. Newer technology is implemented on this chip, and it is well-documented, the performance sounds promising
BNO055 breakout board is the most easy to use breakout board since it has on-board data processing. Make this board stand out in the non-Arduino/Raspberry Pi development scenario.
MPU6000, ICM 2094820602, and BMI270 are all good traditional chips
