I like short actions. There is nothing wrong with long actions, I just prefer the shorter fatter cartridges and believe they have greater accuracy potential. It is reasonable to believe that the shorter action should be stiffer than a longer one. And any weight saved is a plus. I guess the main reason is that my favorite cartridges are all short, with the exception of the 6.5x55, and it would be silly to house a .223 rem., 22-250, .243 Win, 7mm-08 or Winchester Short Magnum in a long action.
