Is there a difference in taste between female and male beef?
Per this link from MSU;


  heifer carcasses had slightly more marbling than steer carcasses, but
  USDA quality grade was not significantly different.


So not enough of a quality / taste difference to bother with...


  live heifers averaged $149.80 and steers averaged $149.70 per
  hundredweight


Apparently, heifers (female) are more expensive than steers (castrated male)... by 10 cents per hundred weight.
