Do I change my email, or just use "@outlook" alias?

I can Imagine someone might think this irrelevant, but I take it seriously.

Do I change my email address to "name.surname@outlook.com", or just use that as an alias?

Problem is I have a WP. I don't have any purchases (my debit card is not good enough for MS), but I'd still have to loose all the settings and messages. Is it worth it, what do you think?

I don't really have anything against hotmail, but outlook just sounds better. So basically "better soundness" is te reason wy I'm contemplating this :)
