Aloha,

It would all depend on how far north you grow at. I prefer regrows, But I have a long enough time to get my first harvest in, cut them back, and leave bottom branches to go long and pull a second large harvest in October.

It does take time to go from flower to vege. If you live with a short growing season I would not recomend doing this.

As for clones from regrows, once the plant is back in vege mode, they will yield the same as any branch clone.

Here is a before/after of one of this years regrow. I harvested 2 ozs off the top and the three branches I left behind will yield lowball a lb come October.
