do you use live distros often and why.

As above, sometimes you just need the right tool for the job and having the live image can be handy. I tend to just have the ubuntu installer loaded on a usb stick at the latest version ready to go.

I distro hop always have to check out a new Linux OS. Live USB is the way to do just that.
Always try a new version of Ubuntu on a live USB. Another way to look at it gives you your own OS in your pocket to use anywhere without any worries or doing anything to a different computer. Still being able to save your work on your own OS. I do backups on a USB which are live, snapshot of the OS, which include everything including all of the updates.
