need list of usb bootable Operating Systems

I am looking for a good list of operating systems you can run from a usb or dvd.

If not a list, then folks can just post their top picks.

I want these to run from the usb/dvd without installing on the system or getting in the way of the system that exists on the hard drive.

Thanks in advance.
