I would recommend Manjaro linux, it's slicker and faster than the Ubuntu derived distros out of the box, it's running on Arch Linux, so has a wealth of information and very well stocked software repositories behind it, however it's also much more user friendly and far faster and easier to setup and get stuck into than Arch it's self. It has a graphical package manager, although pacman is so good I'm not sure why you wouldn't just use that, which is of course included. There are a few flavoures available, I use the XFCE one, myself, which I think is probably the most popular.
Not sure what else to say really, I like it, it's great, don't worry if a lot of what I said didn't mean much to you, it's really not hard to get it setup and I think it's perhaps a better bet for getting a reasonbly user friendly distribution while still also having a good reason to learn to start using the CLI a bit, even if it's just for pacman ...which is the Arch package manager and is much, much better thna the GUI one Manjaro also has. Manjaro doesn't hold your hand as much as Ubuntu and it's spinoffs, but it does so far, far more than Arch does, however when/if you start to want to make more extensive changes to it, you can use Arch literature just as easily as Manjaro's own, and there is a LOT of stuff write about Arch.
if you fancy going for a bit more hand holding and want to go with a nice easy Ubuntu based distro, with massive repo based software support I would recommend Mint like everyone else.
