I don't think you can go wrong with either one! I compared them both, and they seemed to offer the same features, so I went with the less expensive one at the time which was Zenfolio, and I've been very happy with them.

They are both very customizable and you can use your own domain name as well. If you don't use your own domain name, then I prefer the Zenfolio name brand, because it just sounds more professional to me and less consumer oriented like smugmug, since many amateur or parent photographers have smugmug accounts (just my opinion).


Zenfolio also offers Aperture, Lightroom and Photoshop plug-ins.
