Alembic vs Vertex Animation from Houdini to UE4 or Unity

Happy New Year fellow vfx artists.

What is more efficient Alembic or Vertex Animation? I have only done Alembic format from Houdini such as cloth and destruction simulation to the UE4.
I would need to do vertex animation for destruction from Houdini to UE4
Which way is cheaper, more efficient and or better workflow?

Thank you
