Maybe if all things are equal. But, we are talking theory here. We had a similar discussion in my guild yesterday. The reason I picked a Half Elf female for my Berserker, is because I think it's funny as hell when you are in a pickup group, and out tanking someone who picked a "proper race" and the "best class", and they get all huffy cause a little girl is doing a better job then they can. Just being a Barbarian/Ogre Guardian doesn't mean you are going to be the best tank. Gear, and skill play a major role. Good gear of course means a lot. But, so does skill. Having more defense than god means nothing, if you aren't being hit. A MT needs to be able to hold aggro. It's easy to hold aggro agains one mob, but what if you are fighting 10? Who's going to do a better job then? I'd say,the one that procs an AoE taunt, has rampage, and several AoE attacks. In my guild, Berserkers are the main raid tanks. Seems to work just fine. There is very little we can't take. And, if we can't, it is usually not the tanks fault. It's lack of intelligance. After a few trys, we will figue the key out.
