chorus is easily as "good" as ultegra, i would argue its better, but thats a can of worms. record is essentially the top of the line. i was surprised to see the pro's ride record as opposed to super record, so take that for what its worth. you cant beat the durability and functionality of campy stuff, especially chorus, its a fantastic group.

and no, dont mix campy and shimano stuff, if your going to switch over, make the commitment or stick to shimano/sram
