Lovable font-family for your site

When I design a website or more in general a graphic composition there are two things which bother me: the color palette and the font-family.

After some trials I find a color palette which satisfy me pretty simply but when I have to choose the font...

The winner is...
In general my choice is always limited to "Arial" or "Verdana" but sincerly I am used to using Arial font-family with size 12px or 13px for text body and 18px with font-weight set to strong for text header. If you like how this font looks on sites like delicious, digg, flickr, "Arial" is your perfect font :)


Verdana
I like how "Verdana" looks... but only for to size smaller then 12px. I think the perfect size for this font is 11px with a line-height set to 16px-18px. I don't suggest it for the text body: it's small and can result difficult to read with this size for some users.

You can see a good use of Verdana font on A List Apart and the result is very elegant.


Lucida
Recently, how you can also see on this blog, I am addicted form this combination of fonts: "Lucida" with size 12px for text body...

font-family:"Lucida Grande", "Lucida Sans Unicode", Verdana, Arial, Helvetica, sans-serif;
font-size:12px;

... and "Georgia" with a big size (32px, 36px...) for text header:

font-family: Georgia, "Times New Roman", Times, serif;

And you, which font-family do you prefer? :))
