I was a long time flickr user, and still have a pro account there. But about a year ago, I switched to Smugmug because I got tired of the flickr’s graphic layout. Smugmug is not free, but so much easier on the eyes. I have the power account, which is $60/year but they have a 30 day trial in case you are on the fence. There is a lot I miss about flickr, like the community, especially seeing my friends’ updates, but in this case, better design won out.
