The lower ratio (9:1) will give a faster moving robot.

...operating with the unwritten assumption that all other things are equal.
A robot with a 9:1 ratio and 6" wheels will be slower than one with a 9:1 ratio and 8" wheels.
I give presentations about drive train design now and again and I sometimes assume a level of understanding that's not there yet, so I just wanted to explicitly note that gear ratio alone does not determine a robot's final speed.
