Possibly my dullest question ever on MN 
We are ordering pull out larders for our new kitchen and they come with either regular solid shelves or basket-type metal ones. What is the benefit of having the baskets? Air circulation? Easier to clean? Better to have half and half? I'm imagining if used for things like cereal/flour etc. if it spills it'll be messy and just end up on the floor or maybe that's better than having it spill all over the shelves?
Please enlighten me
