I personally prefer any AY J cabin over any BA Club World except upstairs on 744. Now, I am probably in a minority, as many people like BA. And that doesn't mean AY cabins are anything great. But anyway.
As for "old" A330, chances are there are none left in August, as they are supposed to be retro-fitted during H1 2014. We have currently no evidence AY is on schedule with this, but they have publicly said so and not redrawn from it.
