Transform vs ReplacementTransform
The difference between Transform and ReplacementTransform is that Transform(mob1, mob2) transforms the points (as well as other attributes like color) of mob1 into the points/attributes of mob2.
ReplacementTransform(mob1, mob2) on the other hand literally replaces mob1 on the scene with mob2.
The use of ReplacementTransform or Transform is mostly up to personal preference. They can be used to accomplish the same effect, as shown below.
