The Darings do indeed look bigger vessels than the Burkes. I was quite surprised by this when I first noticed it. I believe that once the Darings have their problems ironed out, they will be some of the most formidable AAW Destroyers in service anywhere.. mind you six don't stretch that far! The Burkes, currently running to over sixty hulls, are a pretty potent general purpose destroyer, unlike the predominantly single role Darings.
In a 'smacked around with an ugly stick' competition, I have always fancied building a Burke, good looking ships, however, the stark lines of a Daring have now taken over in my 'likes' department. They do look impressive at a distance, not so good up close though..
