Memory usage in FF with lots of tabs seems a bit better than Chrome, CPU usage seems a bit worse. I think the UI does a significantly better job of handling them though, since Chrome just shrinks everything until there's no text left.
About a year ago FF was really awful with lots of tabs, CPU usage was very high and the UI would occasionally freeze up for 10+ seconds at a time. They're really been making some big performance improvements lately.
