Pros
Pro Open source
Both Kodi and Ubuntu are free and open source.
Pro Updates can be run remotely
Using a Linux distro (not only Ubuntu) with Kodi allows you to run system and software updates remotely through SSH. Not only that, it's also very easy to update the system because only a couple of commands are needed.
Pro Free and open source
Mythbuntu is an Ubuntu flavor of MythTV. Both MythTV and Ubuntu are completely free and open source, so by extension Mythbuntu is open source as well.
Pro Customizable
MythTV (and by extension Mythbuntu) has plenty of modules that allow users to display photos, listen to music and watch movies. All of this is done from the main menu.
Cons
Con Sub-par graphic drivers support
Support for graphic drivers is not the best. For example, if you want to do any gaming on Kodibuntu you need an Nvidia card and install the proprietary drivers. Though for Kodi alone the Open Source drivers are good enough.
Con Dated UI
The UI is dated and not very pleasing to the eye.
