From what i have tested MRD / GLA are now very similar in holding hate, MRD just edges it as they do more dmg and are easier to manage they also can use flash/provoke just like a GLA can. I have found that GLA takes a lot more button mashing to keep up with MRD so may not be the best choice for the larger battles. However with the introduction of jobs I do believe that PLD will be king of tanks.
