there's probably no significant difference except with removechild the object doesn't have a depth.

despite using each, the objects still occupy memory and affect frame rate.  flash still needs to keep track of the positions of both and they both can trigger positive hittests.

neither needs to be drawn so it's better to use either than set the alpha to zero.
