Better? I doubt it, maybe for the inept or challenged. For the occasional coffee drinker, they probably think so. For a serious coffee drinker like myself, definitely not. I think the adavantage is convenience at a high price. In my opinion, a quality bean, freshly roasted (dark) and ground just before being brewed in a drip maker is the best. I also have a 'cafe presse' which I enjoy when I want something slightly different. Back in the 1950's when most Americans used percolator coffee makers (the worst possible method) I became a believer in the Chemex method (hourglass shaped device and round chemistry lab filter paper folded into a cone) which required the user to pour 195 F pre-heated water in a carefully prescribed method according to the chemist who developed and marketed the device. There was a world of difference. Today's modern coffee makers mimic this concept, and do it pretty well. The Keurig device (and other similar) has simply taken this another step in the name of convenience, for the occasional drinker. I find the high cost of the coffee to be silly.
...Just kidding; it would never happen here at our site.
