Which Navigation is best?
 

If you design a page with multiple text link menu choices which is better for clicks from a customer point of view?

Top across the page, bottom duplicating the top links, left side down the page or right side down the page...?

I've heard arguments for all, so I thought I'd ask here to see what the experts say...

Any advice on which clicks best?

left navigation would probably be the most famliar UI if you have the real estate to spare
