My rabbit has a bowl - I think they prefer it because it is easier to get at the water and some times the nipples on the water bottles can get stuck, meaning no water, or it all floods out in one go. Just make sure the bowl is heavy so they can't tip it over, but not too deep (I use a ceramic cat food bowl), as if it's too deep they end up having to stick their noses right into the water and sometimes breath it in resulting in snorting fits. Shallow, heavy and filled to the top is the best bet.
If your rabbit will only drink from a bowl, don't forget to tell your vet if the rabbit has to be an in-patient for a while. Mine went in for an anaesthetic and spent all day in a cage with only a bottle that she didn't know how to use. Luckily I popped in to visit, and asked for a bowl - she was gasping for a drink by this stage..
