As with everything in fluid dynamics, it depends. If you introduce turbulence on a golf ball it stalls flow separation. Conversely it induces additional skin friction or parasitic drag effects. Introducing turbulence early into the flow will promote skin friction but also encourage flow separation later as well, potentially. It can also expand the boundary layer substantially more...

This would need to be checked with some good CFD or real testing.
