which is the best font to use?

i have started a new project aimed at woman and i have become torn between which font to use for articles that require intense reading..

arial, verdana, or some other?

arial looks nicer, but verdana is easier to read in my opinion. what do ya'll webmasters think, and which do you prefer?

site is currently on arial at: http://www.pregnantwoman.co.uk/

 

Verdana or Georgia are too most common readable fonts, with them being sans-serif and serif respectively...

 

Also look into Google Fonts http://code.google.com/webfonts if you're looking into something fancy.
