The Royal Navy has been conducting a rather absurd PR campaign for these ships, IMHO. So far only the hull of the first of class has been completed, receiving mission systems (radars, command & control systems, armament and other sub systems etc) installation and integration. Type 45 will accomodate new technologies, i.e systems not used before, not tested before, not combat proven.
In addition, promoting some features like DVD players, iPod charging stations, enhanced crew accomodation etc serves only one purpose: Attracting more men and women for a military branch based on professionalism. Keeping in mind that that branch has been on a steep decline in terms of budget and assets (both air and naval), such active promotion like "the very very best AAW destroyer in the world! so best that we cannot afford much and cannot provide fixed wing air cover" makes more sense.
Type 45 is a promising ship though. But it is more than early to claim that it is the best right now. It's hull maybe the best AAW destroyer hull in the world, though, nothing more.
