Plastic junction boxes for lights

The Home Depot guy working the electric section saw all the metal boxes in my cart for my new bathroom and convinced me that plastic is definitely the way to go. I think I'm sold on the plastic boxes for my switches and receptacles. But, do real electricians use plastic boxes for light-weight light fixtures in a bathroom for new construction?

New work or old work boxes. If new work, nail on or bar hanger?

New work box. Here's what they sold me. Might end up needing a bar hanger once I see exactly where the joists are. Would that make a difference to you regarding plastic or metal?

Plastic boxes are fine. They also do not require grounding.

That is fine if you need all your boxes next to a rafter or joist but if not you need a bar hanger box.

I prefer the metal 4" octagon boxes over plastic round boxes. I seem to recall that some fixture mounting studs would hit the egde of the round boxes and were a real PIA, but they would miss an octagon box. I also feel they are more solid. Old school maybe, but that is my opinion.
