I don't think its superior. Superiors is Cap's or Slade IMO. I'd say better but superior might be pushing it. As I consider DD's speed better then Bruce but not superior.
That's my mistake I used the wrong word here. I didn't mean that Bruce's endurance is so much better that he outclasses Matt's but rather that he has an edge on him just like Matt has an edge on Bruce in agility. I agree with you. As I said before, overall they're pretty evenly matched physically anyway.
Tell me about this "Survived a reinforced trap room full of lethal gas without his utility belt" sounds pretty impressive how did he do it?
Determination more then anything I'd say. He barely survived and was unconscious btw but he managed to come out of it alive no less. There was another time when Ra's trapped him in an ozone death chamber that he escaped from using a yoga breathing technique and escape artistry.
Hold a minute. Arent Omacs supposed to know the weaknesses and areas to hit of all the heroes?
Batman one weakness has always been that he's human (although an exceptional one) which is why the OMAC drone was able to overpower him. Although they originally sent more then one to take him down and capture Sasha. Then again, I'd say there's a reason for that since Superman once refered to Batman as the world's most dangerous man when the White Martians laughed at him being a threat to them since he was only human according to them. I don't think Max wanted to take any risks with Batman.
Speaking of OMAC, here's Batman OMAC file and how they rank him:
