I tried out Smugmug, starting earlier in the year. Over the summer, they got really slow to process my photos, and I'd get pics stuck in processing. When I contacted their help desk, they told me it wasn't happening (even though it was right in front of me). I cancelled my pre-paid annual service today, and they will not give me a refund on the balance. It wasn't much money. I'm not even sure that's legal in terms of subscriptions, though likely I agreed to it in a click-through TOS. I would not recommend them.
