I watched an impressive video on using poly groups in ZBrush to remesh some CAD objects. Honestly though, when I just want to get a good render and really don't care about having the mesh for other uses, it seems like a lot of work. I can't justify the time for that. I don't mind some triangles, I would not complain if the mesh was all triangles, as long as it renders good.

At least for my application starting with the best mesh output from CAD seems to be the key. If Moi's output is consistently as good as I have seen I'll have to pick up a license.
