Sure, the coffee is fine. The question is one of control for me, not of quality. I like old-school "analog" coffee like my simple pourover or stovetop espresso machine because they are simple devices and, properly maintained, will make coffee forever. A capsule coffee machine is complex, the capsules can't be made by you (and some are triple-packaged, leading to lots of waste), they require power and microprocessors, and so on.

I choose the simpler method not because the coffee is better (though I'm sure it can be, and many factors are at play here), but because, in a way, it's the FOSS alternative to the bloated, proprietary capsule systems.
