Ubuntu. Started in the Slackware days, tried a lot of distro’s. Got used to debian commands/layouts etc. still happy to move to Centos for security focused installs. I find Ubuntu has a ton of support and general updates that fix anything I can find broken.
Clearly you are not the target audience. For IT pros and tech enthusiasts regularly rebuilding machines and running numerous diagnostic tools from boot, the ability to quickly bootstrap a machines is a massive timesaver. dd is slower and may mean carrying around a lot of usb sticks, something these people all graduated from.
