As noted, this stuff is cyclical, with the postioning of the 3 players changing through product cycles.
Right now, SRAM's niche is lightest 11 speed mechanical group, and they also have a price advantage over Campagnolo, and typically Shimano.
Obviously, SRAM's behind on electric, but wireless could allow them to leapfrog, until Shimano or Campagnolo comes out with a new electronic groupset, and the cycle continues.
