Agreed also - with one reservation.
I have a Mk 1 Superb with the 130PS AWX engine and confirm others' observations concerning performance and economy - quite exceptional in both cases. (53 mpg over about 1200 miles on holiday, cruise set to an indicated 75 mph on motorways).
In retrospect, insufficient attention was given by VAG to the camshaft and camshaft bearing loadings, such that even with the specified 507.00 oil, valve lobe and camshaft shell bearing wear is always evident when examining an old engine. I think the engineers must have had an overly good lunchtime at the pub - the valve cams are too narrow, and the journal shells are cut out for the cam followers at just the point where the injector lobe loads them.
However, with decent maintenance and correct oil, these engines are good for over 200k miles - and I have driven an untouched Mk 1 Superb AWX with over 300k on the clock (airport taxi).
The DPF killed the PD engine principle as no pressurised fuel is available for a soot burn out when the exhaust valves are open. It's a pity, because there are so many advantages with this system of fuel pressurisation, including extreme durability.
The 4 valve head, balance shaft saga and Siemens injectors all conspired to wreck the poor old PD - maybe the original engineers retired and the re-work for the 2 litre was left to the apprentices.
I'm keeping my AWX - my Superb is very nearly as economical as my wife's Citigo - which weighs about half as much and has nothing like the performance.
Design progress? The 1.9 PD gets my vote.
