Linux Mint 18

I honestly liked this edition of Ubuntu, Linux Mint is a team of their own that have taken Ubuntu and turned it into what feels like an OS unto it's self with their own update and software center applications, they roll out their own updates separate from the Ubuntu updates to create a very stable system.

In my opinion Linux Mint Cinnamon looks just as sleek as Windows 7 looks if not more so, beyond the edition there is a Mint forum where you can get just about any issue handled quite efficiently in my experience, I know not every problem can be solved in a day but they get close to doing so.

They have 4 different editions of Mint including XFCE, MATE, Cinnamon and KDE, while I would like to of seen an LXDE version both XFCE and MATE are great alternatives for older/lower end hardware in regards to speed and smooth operations.
