Keurig K-Express
Score: 68/100Rankings
The Ninja PB051 is a versatile single-serve brewer that handles both pods and grounds and includes a built-in frother, making it ideal for specialty drinks. Its trade-offs are a modest water reservoir and plastic construction. Best suited for solo drinkers or small households seeking flexibility in a compact unit.
The Keurig K-Express offers a compact design, quick brewing and a strong-brew option with a generous 42-oz reservoir. Its limited brew sizes and absence of advanced features like water filtration or programmable settings reduce flexibility. Suited for solo users or small households that prioritize speed and a bolder cup over extensive customization.
