Usage
The traditional rule about which preposition to use after compare states that compare should be followed by to when it points out likenesses or similarities between two apparently dissimilar persons or things: She compared his handwriting to knotted string. Compare should be followed by with, the rule says, when it points out similarities or differences between two entities of the same general class: The critic compared the paintings in the exhibit with magazine photographs. This rule is by no means always observed, however, even in formal speech and writing. The usual practice is to employ to for likenesses between members of different classes: A language may be compared to a living organism. But when the comparison is between members of the same category, both to and with are used: The article compares the Chicago of today with (or to ) the Chicago of the 1890s. Following the past participle compared, either to or with is used regardless of whether differences or similarities are stressed or whether the things compared belong to the same or different classes: Compared with (or to ) the streets of 18th-century London, New York's streets are models of cleanliness and order.

Etymology
Origin of compare
First recorded in 1375–1425; late Middle English comparen, from Latin comparāre “to place together, match,” verb derivative of compar “alike, matching” ( see com-, par 1); replacing Middle English comperen, from Old French comperer, from Latin
Explanation
To compare is to look at two things and see how they are similar and different. People compare all the time. If you look at two products and compare prices, you're looking for the better bargain. It is hard to compare who was the better athlete, Michael Jordan or Billie Jean King, because they played different sports. At a museum, you can compare different paintings. If you like your math teacher better than your history teacher, you're comparing the two. If a TV shows is bad, you could say "it doesn't compare" to your favorite show.
