D5 worse or competition so much better?

In the last few months I have become curious. Since I have not driven a diesel engine for more than 2 years now (why also at 2,90$ vs. 2,10$ for petrol) I have lost a little bit of the connection. When the D5 was introduced in 2001, the press and also the buyers overcame themselves with enthusiasm. Super diesel engine with a lot of power, high running quietness, simply in its class one of the best engines. In the meantime one reads here in the forum constantly S I would like to ask you a question: has the claim of the diesel buyer changed dramatically over the last 5 years? Have all competitors revolutionized the art of diesel construction in the past 5 years? I ask myself this also because 5 years in the time scale of the engine construction are actually not a long time. I originally assumed that the D5 would be a good idea. If you are pregnant, you will be able to have an increased half-life.
