Difference between LiveCD, LiveUSB, full-install, and persistence?

I am currently running Ubuntu as a guest vm on a Win 7 host via VirtualBox, but I would like to have a portable version of Ubuntu when I am not using my laptop.

I am unsure as to the difference between the following:

1)LiveCD with persistence;
2)LiveCD without persistence;
3)LiveUSB with persistence;
4)LiveUSB without persistence;
5)Full-install.

I have a USB flash drive (32GB), and I also have empty DVDs lying around. I know that persistence means that data can be saved, but I am unsure as to which option to choose. What is the difference between a LiveUSB and a full-install on a USB thumbdrive and why would I want to pick one over the other? Thanks for any help.

Live with persistence:

You have the portability of live media with a home-folder and possibly other temp storage

Live without:

Portability but no saved anything

LiveUSB with persistence:

Less life out of the USB(a bunch more reads), but very similar to 1

LiveUSB without persistence:

Less life out of the USB(a bunch more reads), but very similar to 2

Full install:

Obviously, a full install to the USB would translate to shorter life since it would drastically increase the number of reads and writes.
