They are both pretty easy to use....once you get the hang of either.
Smugmug rules, I think, especially because of video. Being able to create an autoplay video of the best pictures we have, with our choice of background music, and uploading to our site to show to potential clients is definitely special.
BTW, I do collect smugmug coupons for everyone to use at my smugmug coupon codes
site. Coupons keep changing, but someone new can save 50% ($75) off from the Pro account.
Call me partial, but I like sticking with someone who keeps up with technology, has great features, and not so bad customer service (Smugmug doesn't offer phone support, but email support is pretty quick...but still, you know what I mean).
