Peripheral chips aren't differentiated by user values like the end products that use them. You don't get more preciser sensors in high end phones. Everyone gets the same thing. You pay more only for more materials.
Sensors that are actually a lot better than standard offerings would also be subject to and/ofs of ITAR or EAR or MTCR or local equivalents thereof, so progress in IMU appears to have been stagnating a bit due to that issue. Sony Semiconductor Solutions had a Arduino IDE compatible clustered IMU board that they say you can see rotation of Earth in data, they ended up selling it with scary warnings and without any of the cool stuffs.
There's a fair bit of quality difference between different chips and better chips have gotten cheaper. More importantly, default filtering quality has improved with more powerful uCs on the IMU package, which is what most cheap phone vendors are probably using.
The ITAR stuff is way more fun though. It's great to read between the lines for the intended customer in the datasheet.
This is the correct answer. They're all the same. The notion that Apple has some kind of edge here is farcical.
