I made my first site with WP for a customer. Previously i used other cms software such as cmsmadesimple joomla etc. I can´t say that WP is easier with it´s template system but the fact that there are so many plugins etc made me decide to probably use it more in the future.
I had to code some submenu´s and stuff and tweak some templates but it looks a bit ok but still shaky i think, i also used some plugins and will use more, the site is still far from finished
