Russian or Turkish?

I want to learn one of two languages, that being Russian or Turkish. Notwithstanding the fact that Russian is understood throughout central asia and the eastern bloc, which one is more useful on a global basis? Which one would be easier to pick up as a native English speaker?

If you want to learn an "easy" language, go with Italian or Spanish or something. But I'd recommend you learn a language that you really want to learn rather than what's easier or more "useful", because you won't learn the simplest language in the world if you get bored after a month.

That said, learn Russian out of the two. Cyrillic can be learnt in less than a week, and although grammar is a bitch, it's not impossible.
