Each has its strengths. The Keurig can produce a decent cup of coffee, with the right K-Cup. It is faster, and more convenient ( I use it at my desk in my office where I do not have access to a sink/etc. With the addition of "MyKCup" and the Pod Slayer it can brew any coffee you want it too, Pod, K-Cup, or Grinds.
The POD machines like the OPOD and Bunn have the same flexibility on what they can brew (K-Cup, Pod, Grinds), but since they brew SLOWER by design. They do tend to produce a better cup using the same grinds./water. Clean up on them is not quite as nice as K-Cup but really not bad.
Variety is no longer an issue between them, so it really depends which is more important to you, the speed/clean up of the K-Cup or the final product of the Pod machines.
I think you can be happy with either.
