Quiver dance or shell smash?

Question

I have a smeargle with
Baton pass
Kings shield
Dark void (didnt have any Pokemon with spore)
But quiver dance or shell smash for sweeping?

Answer 1

I think Quiver dance would be better since it increases three stats instead of only two, and does not decrease the defense's which can leave you vulnerable to attacks if you don't outspeed even with the shell smash boost, and priority if you do outspeed.
