A Count is the Norman title equivalent to an Anglo-Saxon Earl. As such, modern England only has Earls. The oldest title is that of Shrewsbury, created in 1442, but precedence is given to the Howard Dukes of Norfolk on account of their descent from an Earl of Surrey who had inherited the medieval earldom of Arundel, deemed to predate 1442. In Scotland the premier earldom is Mar (created 1404). In Ireland it is Leinster, which was created as an earldom in 1316, subsequently (out of period) raised to a marquisate and then a duchy.
