Hello.
Well, I prefer Ubuntu because it is very easy to use , especially any LTS version ( extended support ) . Both are very similar in functionality and performance cuanrto , but only for the above reasons I prefer Ubuntu. In addition , behind Ubuntu is a company ( Canonical ) which gives coherence to alginos important aspects of their development. The ubuntera community is very large and much official and unofficial documentation helps you to clear doubts and to take full advantage of your system offers .
I would recommend installing Linux in its own file system ( create a separate partition on the hard drive ) instead of having it within Windows.
