Why would you not point a linux noob to ubuntu?
Nowadays, lots of distros are just as easy(Debian, fedora, Linux mint), come with all drivers, work on basically all systems, and don't spy on you. Ubuntu isn't as easy to dual-boot windows now too. There's basically no advantage to Ubuntu now except community.
Ding Ding Ding. This is why I still recommend Ubuntu, there's a community and a wealth of knowledge out there for working with Ubuntu.
Though if you are more experienced and deal with nuanced issues you will find often the community is outdated and this is a double edged sword -- a lot of material out there is for older Ubuntu distros and is no longer relevant.
Wubi for anyone searching.
That's the best and worst reason to reccomend ubuntu. The best because it's community is large and somewhat stable. The worst because that community is under the thumb of a corporation that does not seem to understand it.
