I don't get why people try to compare the long magnums with the short magnums? In my opinion they are not supposed to really compete. For longer shots on the plane where a long barrel is not cumbersome, go for long magnum. If you are stalking through dense forest and don't want the 26" barrel, go for a short mag with a shorter barrel that will give near long magnum performance.

With respect to the long magnums, there is (generally speaking) a consensus as to which are the best (or most reasonable for the task at hand). The Question becomes is which short mag is the best?

The ballistic performance of the 3 short mags are very close to one another, which means other factors have to be considered. Apparently the RCM will feed the most reliable because if its rim design? Any truth in that?
