i don't know anything about the site youchose, but the thing I like about smugmug, and zenfolio is that they both have excellent customer service dept. very quick response time, and they both keep backups of photos at 3 different locations, to me that is worth the annual investment, I have a premium account with zenfolio, so that I can sell my event , and prtrait photos directly from the site, otherwise I would just have the base account which really is inexpensive for what you get.
I had a great experience with zenfolio customer service back in January, I was on vacation in Orlando, and needed to copy photos Of Fushu Daiko from my ren faire folder to a seperate folder so The Fushu Daiko webmaster could download photos for their website, I somehow inadvertantly deleted the folder, and all of the pictures{ close to 2000}. Although I still had the originals at home, I was going to be in Orlando for another week, so I contacted Zenfolio, and they were able to recover the photos for me in an hour or 2
