I have both Flickr & Fotki accounts I primarily use Fotki. I like the look and organization of Fotki better.
Only 30.00/ year for unlimited storage upload is simple and the UI is quickly learned.
You have various options for uploading photos, the site supports FTP
you can specify settings, copyright info, even map out your photos location.
There is a built in journal where you can talk about your photos.
Moving and reorganizing photos is simple. you can chose who views which albums, create passwords.
you can puirchase prints for as little as .09c each.
There are Monthly photo contests where winners receive year freemembership, you can vote on submissions, suggest contest assignments..
I have been using my Fotki for 5 years now and love it.

the one negative thing that fotki doesn't offer that Flickr does, is the ability to add comments within the photo, to point out key part of the photo, i find this especially useful when explaining Origami.
