I love Ubuntu. I use 14.04 at the moment =)
My favorite versions in order are: 9.10 (Yep, 3 second bootup best ever), and 12.04 (Nautilus was perfect out of box in this one), and 14.04 (everything except nautilus I love)
Thank you so much for making this website as everyone is so nice and helpful to our questions. Best of luck to you all.
