Which is better for iced coffee?

The K-Duo Gen 2. It has a dedicated Brew Over Ice setting that A lacks. A brews hot only.

Is the Gen 2 worth $15 more?

If you use iced coffee, want a digital readout, or brew large pods often, yes. If you just want pods and a carafe, A does the same core job for less.

Which has the bigger water tank?

B, at 72 oz (2.12 L) versus 60 oz on A. Both reservoirs are removable and shared between the pod and carafe sides.

Do both brew a full carafe from ground coffee?

Yes. Both brew 6, 8, 10, or 12-cup carafes from ground coffee and both have programmable auto-brew up to 24 hours ahead.

Which has better owner ratings?

A: 4.4 out of 5 from 20,917 ratings, against 4.1 out of 5 from 7,228 ratings for B.

Do both take the same K-Cup pods?

Yes. Both use standard K-Cup pods on the single-serve side.
