I personally find it easier to see the gui layout of my disk before I press play. Gparted can queue and execute a lot of changes to get to your desired state. Very intuitive for people like myself who doesn't deal with partition layouts and filesystems on a daily basis.

Don't get me wrong, seeing the layout is great if you don't mind the requirement for a GUI, but the fdisk UI is actually pretty good, too. It also queues and executes a lot of changes to get to your desired state, and it can show all the sizes and offsets that define the partition layout. It's not actually a command line tool, but dialog-driven (you give it commands on-line, get built-in help, etc.).
