Per the article, in this blind taste test, the opposite appears to be true:

In distant last place came the ground coffee I had brought, a very good quality, single-estate bean, but not roasted for espresso and ground four days earlier, a little too coarsely for Bruno’s machine. The traditional house espresso scored 18 points, and was the favourite of one taster. But the clear winner with 22 points was the Nespresso, which both scored most consistently and was the favourite of two of the four tasters. Of course, these were just four people’s opinions. But their consensus fits the judgment of top chefs and Nespresso’s own extensive testing, which must have been conclusive enough for them to have the confidence to agree to my challenge in the first place.
