Generally C1pro doesn’t quite match up to LR or Aperture but does rub shoulders with quality of output. Adobe’s LR tends to get the gold star as Aperture are quite slow in releasing upgrades for new cameras. It comes down to what extracts the best from camera manufacturers Raw files. Not sure also if Aperture or C1pro handles video as LR does.
However if you wish to get the best out of your raw files on an individual basis (no cataloging element) then Iridient (http://www.iridientdigital.com/products/rawdeveloper.html) is darn good.
