I have used almost all of the Ubuntu releases since the 5.0X versions. I went away from Ubuntu around 2012 when the traditional desktop and went to the touch screen oriented display. I was working in software development at that time and was used to having multiple open applications displayed at the same time on a desktop. It was very difficult to do with Ubuntu's desktop.
The Mint releases kept a traditional desktop. Plus the release included a lot of drivers and audio and video applications that were not part of Ubuntu since they are not open source.
The Mint releases are based upon the Ubuntu so most of the help for Ubuntu works on the Mint. Both have very active and useful help forums.
Get several 2 gig USB sticks and use
LiLi USB Creator to create bootable images of the Ubuntu and Mint releases. This allows you to use each for a while to see good or bad in each release. I did this on most new releases so I could decide if I wanted to upgrade before making any changes to my main computer.
The only problems I have had, was with MS Office documents. Large documents with a lot of formatting and multiple fonts can be problematic doing group edits.
