There is a
world of difference in traction between a good and a bad mecanum drive. Proper design and craftsmanship are crucial to traction for a mecanum.

The rollers on mecanums ... will always spin slightly unless you are going perfectly perpendicular to their direction of rotation.

When the vehicle is going at a 45 degree diagonal (i.e. perfectly perpendicular to the direction of rotation of the rollers), the rollers
do spin.
The only time the rollers do
not spin
1 is when going forward and backward, is which case the vehicle is not going perfectly perpendicular to the direction of rotation of the rollers.

It's the same amount of friction in every direction as long as the wheels are locked.

This is not true if the coefficient of friction of the wheels is different in different directions.
1In theory, with no roller axial free play and a non-compliant floor surface.
