I like everything about it! The interface has so many options for customization to meet our needs as well as other user's requirements we can see in mattercontrol community forums or github repositories (if they don't have one). It works great with multiple computers at once which makes managing jobs easier than using some of those expensive third party programs out there such as Ultimaker Cura etc.. There arenโt any downsides from my point if view but maybe someone who knows more will be ableโฆ
Pros
The interface is easy to use and understand also
Cons
I have not found anything that I dislike at this time
