I have used a range of them. MinimalFolio, Foliobook, Xtrafolio are the ones that I liked most, but what made me abandon them wasn't their presentation features - it was the awkwardness and time involved in managing / updating images, which seemed to be Kevin's point. Updating your portfolio is usually very manual, so you don't do it often and have to relearn the method every time.
It's much easier using Lightroom Mobile. Its Present mode isn't as fancy, but it's sufficient. Best of all, LrM automatically syncs with all my devices and I can manage content with Lr on my Mac or PC, in Lr Mobile on the iPad or phone, or in a web browser. To use Lightroom Mobile offline, you just need to enable Offline Editing for any collections you want.
