The rough coats are easier to deal with, and shed WAYYYY less than the smooths. The smooths shed year round. The roughs shed 2 times a year. (for the most part) I never need to brush the dogs, and when bathed they dry very fast, as wire hair doesn't seem to hold water.
Border Terriers. They're adorable little guys with a strong will. My neigbor has a BTx who is a sweetheart, although he IS very controlling and loud. I wouldn't imagine many BT's are like him, though. I've found most to be quite quiet and laid back.
