What is the best email username to use for a myname.com domain?

Let's say I have the domain johnsmith.com and I want people to reach me via email, what is the best email username to use?

Some examples:

• john@johnsmith.com - redundant
• john.smith@johnsmith.com - redundant and looks kinda stupid
• mail@johnsmith.com - makes sense, but looks very "technical"
• me@johnsmith.com
• root@johnsmith.com - for the geeks among us ;-)

Of course, technically I can simply say that I will be able to receive *@johnsmith.com, however, for a better user experience I still just want one email address for public presence (website, business cards, etc.).

Any suggestions?
