Choose one that has a rate just slightly larger than the fastest you expect to see your robot rotate.

Just to add to that, if a fast robot clips your robot and makes it spin fast, your robot can lose its heading. If heading is super important for your robot code, consider using a magnetic compass to provide a lower bandwidth correction to "reset" the gyro heading.

(e.g Davantech CMPS03 or Hitechnic NXT)
