Vector timeline?

While working through the challenge to scale the crystal actor during collection, I grabbed a ‘Set Actor Scale 3D’ node and saw the scale input was a vector. I created a vector timeline, setting the XYZ scale to 1 at 0 seconds, and the XYZ scale to 0 at 0.68 seconds. I then ran this timeline output to the vector scale input on the SetActorScale, and it worked. I’m wondering, is this method slower or harder on RAM? Is there any reason, say in a larger project, that it would be better to use the Lerp method?
