After using flickr, I settled on Smugmug. I can customize my site almost entirely, subject only to my own skills. Every page on Smugmug is completely customizable, I can determine the look and layout and make it different on every page if that's what I want.
There is little or no ability to customize or to use your own Domain on Flickr.
Be aware that Smugmug adds more capabilities as you pay more, I use the power level for $60 a year. The basic level for $40 a year is more limited, I'd pay the $60 and get more features. I even use my own domain www.mount-spokane
I also find that Jeffrey Friededl's uploader from Lightroom adds a lot to the ability to effectively use lightroom, since you can set most parameters like size, sharpness, titles, etc before you upload the images.
