Hilton HHonors - Which Abu Dhabi Hilton do you prefer?

I've a 3 week trip pending to Abu Dhabi in March, and am looking for advice from anyone who has stayed at the Hilton Baynunah or Hilton Corniche.

I stayed at the Hilton Abu Dhabi last year, and am already familiar with that location. But these other two are closer to the city center where I'll be working.

The Cornish is much closer (walking distance) to other real hotels (Cornish is a hotel/residence) for those looking for an after dinner drink. Also has outdoor pool on the roof for those wanting to take some sun.
