J.R. Ewing or Gordon Gecko

Two of the most cold blooded and coniving businessmen in the fictional world, but which one is the dirtiest player in the game and gets the upperhand on the other should the two go to "war".. I say J.R., the guy would sell his own flesh and blood brother up the river to get what he wants, Gecko showed in Wall Steet 2 that he does indeed have a conscious and that could come back and bite him in the arse against Ewing.. Not to mention J.R. also has the Dallas Cartel and many other independent rich oilmen on his side (they may not like him, but they know when Ewing Oil gives walking orders its best to fall in line behind them), I could be wrong but I just don't see Gecko getting support from any rivals in the investment world to take J.R. down. What say you M/TV Board?
