For gdisk: GPT fdisk (aka gdisk) is a text-mode menu-driven program for creation and manipulation of partition tables. It will automatically convert an old-style Master Boot Record (MBR) partition table or BSD disklabel stored without an MBR  carrier  partition  to  the  newer  Globally Unique Identifier (GUID) Partition Table (GPT) format, or will load a GUID partition table. Odds are, you can likely use either tool but if you are using GPT, you may as well use the tool made for that purpose.  I think a lot of it is very similar as far as options that do the same things in each program.  Also, there is also cfdisk and cgdisk too.  The interface is different.  You may want to try the proper one and see which you like.  I use c*disk tools myself.  You may prefer the others.  Same result I guess.  Hope that helps.
