The Murata sensors don't seem to be much better than the Tokin sensors,
at least accoring to the data sheet. 20% variation over the operating
temperature range, 5% non-linearity, and a scale factor of only
0.67mV/deg/sec. With that scale factor the signal to noise ratio is
going to be a problem and you'll need a temperature sensor too. Although
I guess it really depends on how accurate you want you're IMU to be. If
you do go with these gyros I'd be curious to see what kind of results
you get.
What kind of application are you designing for?
