If a golf ball and bowling ball are moving and both have the same kinetic energy. Which one moving faster? If they move at the same speed, which one has more kinetic energy?

KE = 1/2 mv^2

So in the case where they have the same energy, the golf ball has less mass, so greater velocity to make up for less mass.

If they are moving at the same velocity, the only variable that differs is mass. The ball with more mass has more KE.
