We've been using the Supreme Plus for just over a week now and couldn't be happier. Coffee is strong but not bitter (Bustelo espresso blend for me and Dark Magic for my husband), and the program option makes it foolproof. It has a smaller footprint so my counters are thanking me.
Not sure if it's in my head, but the coffee does taste better in my opinion than our previous Keurig coffee maker (that we kept pretty clean). Seems to have more flavor. If you need a new coffee maker, I'd definitely recommend this one.
