We've used that gyro for several years and it's been good enough. I think we've put it on 2 6WD designs and two Mecanum designs. It's purpose was the same as what you intend - to assist in going straight over uneven surfaces or when getting pushed around. The analog interface makes it pretty easy to use.

The Analog Devices ADW22307 is an old gyro and I don't believe you'll find one much longer. It doesn't seem to exist on the Analog Devices web site. Most of the new stuff is smaller, MUCH cheaper, and uses a digital interface.
