Zenfolio as one big pro argument: unlimited pictures and videos for all plans. And starting at $5 per month, that is a pretty compelling offer. The downside is that customer support from a real person is only available on the highest plan ($30 per month for an annual payment), which is a pretty big one in today's competitive landscape. Most service providers already know that outstanding customer support is one of the things that can really set them apart, so it feels like Zenfolio is dropping the ball here.
The themes are a little stale and there's not a lot of customizing you can do. Also, the editor is a bit confusing, it's a bit difficult to find your way around it at times.
