I use and like Gnumeric- http://projects.gnome.org/gnumeric/ http://projects.gnome.org/gnumeric/ it tends to be lighter and faster than the Open Office equivalent and I haven't found any features which it lacks. Excel has more prettiness options for display/print but from what I have read Gnumeric beats it's pants off in terms of math and statistics functions.
