Who moves faster; Crash or Coco?

Solution 1:

Playing as Crash vs Coco is purely a cosmetic difference. While the animations differ, the actual moves and movement are the same.

From this list of version differences:

Coco is now fully playable in all three games. She controls just like Crash, but she has her own unique animations.

From this thread:

Are there any gameplay differences between the 2 or is it purely cosmetic?

Cosmetic.

Sadly, yes, it is cosmetic only. Do you want to play as a male or a female?

And from this thread asking the same question as this one:

Is it just me or is Coco faster on the Monkey bars?

Her animation has more motion in it, but the actual physics engine movement speed is identical. It's a minor optical illusion.
