I prefer to use a touchless garbage can in places where germs and other contaminants are likely to be found, like the bathroom and kitchen. Other places where the garbage is likely to be mostly paper or other non-hazardous materials, like the office or living room, will have decorative garbage cans. The outdoor garbage can is most likely going to be metal, and the yard waste will go into a large plastic garbage can.
To me, there isn't any one material that works for all garbage cans in my home. Plastic is easier to clean than a wooden garbage can, but isn't always very attractive. A metal can will hold up to a lot of abuse, but I don't want one in my house.
