Drivetrain gear placement

Is it better to place the gears for a drivetrain facing the inside or the outside? I have seen teams do both, but have always done inside. Are there any benefits for making them face the outside?

I think most teams do gear out just for looks, but ig it technically makes your robot turn faster due to the wheels being closer together.

It makes your turning slightly faster because the arc the wheels have to cover is shorter. It also has smaller benefits like supporting your robot’s weight closer to the middle and of course looking better.
