WHBM, I agree.
I have flown SU two months ago (London-Moscow-Hong Kong) and the service was very good, as well as the aircrafts (320 and 330).
As a result I booked another "series" with them (London-Moscow-Shanghai).
They have improved considerably since I used them early 2000 (Venice-Moscow-Hong Kong). At that time the Venice-Moscow sector was flown by TU-154M (superb bird, I loved it).
However I would not recommend these routes if the transit time is longer than 2 hours. The new Terminal D has not been completed yet and the business lounge is not available.
SU ground staff told me it will take some "russian" time to complete it
