I have stayed at the Hilton Beijing Wangfujing (Oct 2012), and I can say without a doubt that it is the BEST Hilton I have EVER stayed at. As HHG, they upgraded me to a suite (I think I already booked a King Plus or similar). On arrival, I had a high-tea style arrangement of little treats in the room, and no less than THREE welcome notes (one typed general note explaining my benefits, one hand-written welcome card explaining my treats, and a hand-written card from the GM, which was very stylish).
The bath and shower (no, not a 'shub'), was a separate 'room' within the bathroom, and had a TV. The bathroom had his-and-her sinks, a double door entry, the minibar was an entire cabinet, and the room was *huge*.
The exec lounge was at the end of the top floor, and gave some decent views. I believe there was a coughtail hour and some other niceties, but I was more interested in seeing Beijing (I did still use the lounge for my free Diet Cokes after a day of walking). I'll dig up my benefits letter and give you a few details.
As a gold, you are allowed to have breakfast in the main restaurant, which is simply a phenomenal spread (both western and Asian dishes), and there are egg chefs, and the restaurant is very well-appointed.
I'll post a few pics here tomorrow (or rather, later today), but you really won't be disappointed with this hotel.
Also, the GM emailed me about a week before arrival to give me an early welcome to the hotel, and mentioned that I had already been approved for a generous upgrade, and offered their personal contact details should I need any assistance. They also sent through printable (Mandarin) cards to hand to taxi drivers, which I didn't have to ask for, and offered to arrange transport from the airport (which I didn't need).
I would literally fly back to Beijing just for this hotel...... and I'm serious haha!!!
I have not stayed at the other PEK Hilton, though why would I?

They were also building a Waldorf Astoria just next door (I'm not sure when that opens), so perhaps have a look and see also?
