It depends on a few things, but I will simplify so you can decide for yourself

Smaller pinion increases acceleration but will give less top speed
Larger spur gear increases acceleration but will give less to speed

Larger pinion decreases acceleration but gives higher top speed
Smaller spur gear decreases acceleration but gives higher top speed

This is generally speaking as it is possible to overgear your engine.

Pinion & Spur Size play an important role in acceleration and top speed, but the biggest change from the previous generation of cars has been the internal gear ratios. Dropping the internal gear ratios from the 2.50 ranges to 2.00 range has dramatically improved acceleration in our cars. It translates to lower spool up time of the drivetrain to reach the same speed.
