Dave Studeman at The Hardball Times ranks the top 40 pitchers of all time, according to Win Shares Above Bench since 1900.

Three Cubs show up on the list (only including those who played at least a significant portion of their career with the Cubs): Greg Maddux (#8); Mordecai Brown (#13); and Ferguson Jenkins (#23).

Walter Johnson is, of course, number 1, which reminds me of the wonderful biography of Johnson written by his grandson Henry Thomas, Walter Johnson: Baseball's Big Train.
