Which one of the New Vegas companions do you think has the best backstory?

Even though Boone is my favourite companion, I think Raul has the best backstory - one of the few cases where I ended up choosing him a route which I think would bring him peace over the one I would prefer to have (I made him stay a mechanic as I thought it would be ease his suffering the most, despite how cool having a Vaquero ghoul would be).

i like dog\god from DM. i picked ed-e because of his ties to LR.
