Problem nowadays is that changing partition tables is so rare that parted changes their commands between uses, and I never remember if fdisk nowadays has all the GPT related issues that made me try parted in the first place ironed out. Plus I can't remeber the new GPT commands and partition IDs.

I still mostly just read the help text every time because nothing else is installed - but from the speed I might be a bit faster with a well designed GUI nowadays if it is about modifying GPT disks. MBR disks I still can do with fdisk in my sleep.
