This poll has been done before with a more complete list. I only mention that since my favorites are not on it.
1. Ambre Nuit by Christian Dior - an incredible amber. Rich and deep but at the same time not too sweet and dominating. Easy to wear to work or on nights out.
2. Amber Absolute Tom Ford
3. Ambre 114 - do not buy a full bottle of Blue Amber or Ambre Precieux without trying this first as they are very similar but I prefer this one.
