The thing is that the weight behind the axle causes a lot of inertia on the rear end. It's completely true the inertia results in added stability. However, if you hit the threshold that the car gets out of balance - which inevitably the car will on a low bite bumpy track. It could be either because the rear end loses grip or that the car hits a bump very hard, but the end result is the same: the inertia that helped you before will make it very hard to correct the car because it's been corrected by a force big enough to unsettle it in the first place.
Every MM car I tried seems to suit me better than RM. It loses traction earlier and is more easily unsettled, but in a smooth, forgiving manner. It's as if the MM car announces the necessity to correct the car to keep it going in the right general direction, which gives you a zone to control how settled your car is. In contrast, the RM car pretends everything is in check, then suddenly points it's nose in the wrong direction like a stubborn mule and reports to you that you've exceeded the physical limits of the car's stability.

It really doesn't matter which version you have on a bumpy track. Its a matter of your suspension tuning and weight balance.
I agree that a RM car will have more weight in the back which makes it easier to swing around, but its about balancing the car. With RM we tend to move the battery full forward on low/med bite which stops the car from rotating too much. As for hitting the threshold, it really depends on your roll center and shocks. Having too much roll can make the car hook in corners, so if it starts to hook, maybe you need to stiffen the rear a bit more with a heavier spring and go up a weight in oil. The MM has most of the weight in the middle so it can run a slightly lighter rear end shock package. You just can't change the motor from MM to RM and expect it to work perfectly.
But the advantage of RM is being able to get on the power faster and hard than others and using that to your advantage. Don't get me wrong, MM is good. It carries way more corner speed, sure has slightly less grip, but it is more consistent with the grip it has. MM is also better thru chicanes and high speed sections. If I ran MM, I would try to carry more corner speed, take a out in out approach on corners while the RM I can just hug the corner and punch it out.
It really depends on the tracks you race on. European tracks tend to be more fast and flowing thus favoring MM, while US track are more 90 and 180 turns which favor RM.
