The machine makes good coffee. This is, of course, the most important aspect of a coffee machine. It's simple to use (finding the menu takes a bit of searching at first, but after that, it's straightforward).
The machine has several coffee recipes. It's not as extensive as some competitors, but that can be a plus. It helps with choosing the right one.
There are several regular coffee options and a few milk varieties.
The Jura is easy to set. While brewing the coffee (after making your selection), you can use the buttons to adjust the amount of coffee and water. This can be adjusted to your preference to make the coffee just the way you like it. I personally found myself relying on Jura's own settings. I also assume they've done more research than I have. The taste is good, but this obviously depends heavily on the beans you choose.
A small drawback is that everything about this machine is quite compact. This makes emptying the drip tray difficult, the water reservoir is small, and the coffee spout can't be positioned very high for tall glasses. The downside is that it's not a colossal appliance on the countertop. Choices...
The appliance's maintenance is fine. There's no removable brewing unit, so emptying the drip tray is practically the only maintenance required. A plastic container is included for cleaning the milk system. While it works well, it's not the fastest system. You have to fill a container with water, which is pumped through the system (connected to the milk hose). Then you empty the container, and the system rinses again. Some competitors offer faster and easier ways to do this without any intermediate steps. It's a minor point of concern, and for me, it doesn't detract from the overall convenience of this appliance, but this can vary from person to person.
The internal, fixed brewing unit is sometimes a point of contention. If it's impossible to clean, how dirty will it ultimately get? I can't comment on this specific model yet. I've taken apart previous Jura models, and it didn't make a significant difference. I'm not worried about the C9 in that regard either.
I find the on/off button, located on the top left rear of the appliance, a unique choice. Design-wise, it works well, but functionality in small kitchens is a bit less so. It's not the most important feature, but perhaps something to consider depending on the placement.
