I have both and use both. For differennt things.
ByeBye I sometimes mix with Maybelline Age rewind for a silkier texure. I find that the Bye Bye mixes better than Shape Tape. Shape Tape is for heavy duty coverage, but I rarely bake it. I find that if I set my concealer immediately, no matter what it is I get less creasing.
