I started with F19 in May, when the alphas were released. Fedora 19 is a very solid distribution. I immediately liked the anaconda installer, and except for some minor quirks with some features, I found anaconda great. In a similar way, Fedora 19 is great. After using both Gnome in F19 and KDE, I elected to go with KDE. It is just a matter of personal preference. With Fedora 18, I chose Gnome over KDE. As I indicated, it is a matter of preference. I did try other DE's such as cinnamon, which again, but when I did my testing, cinnamon was unavailable to test. I will wait a few weeks and then give cinnamon a try.
