Reading (and writing!) datasheets is both an artform and a science, and requires a heavy dose of skepticism and attention to detail on the reader’s part. Comparing similar parts should be easy by just opening all the datasheets up, but as you’ll see in Comparing Gyroscope Datasheets, it’s rarely straightforward, and usually takes a lot more effort than it should.
This learning guide was something we put together just as an internal comparison, but we wanted to publish it as an interesting study in comparing terminology and published figures (or the lack thereof) to compare what you think a silicon vendor is giving you, with what they’re actually guaranteeing (or what they are avoiding giving any guarantees at all about!).
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

I don’t think you can assume that gyro drift / zero offset is going to be stable on any of these devices across temperatures.
If you want the lowest possible gyro drift then you have to measure and calibrate manually or use any available built-in calibration, e.g. the MPU9250 has an option that can auto calibrate the gyro (DMP_FEATURE_GYRO_CAL) when using the DMP (on-chip sensor fusion).
