Cups or Nipples?

[Chicken Man Can]

I am going to replace my flock's water bowl with an automatic system via bucket, float valve, and hose. I am deliberating whether I should use nipples or cups. Anyone have experience with one or both of these, pros cons?

Do you live where it freezes? The water in cups can freeze but the nipples in my heated bucket have never frozen and I live in Ohio.

Same here in Wisconsin.
