I like how personal it makes things look, not just with my clients but also myself in general! The website looks very pretty to me as well (which always helps).
It's so easy for people who are new or don't know too much about design/photoshop etcetera - they can easily pick up what you're doing because of all of those options available at their fingertips. That being said there might be some more ways to customize elements within each page if wanted by client-side developer? Not sure though since haven't had an issue yet :D Very quick turnaround time from initial concept & ideas via prototyping until final implementation which was seamless process overall :).
