Which fountain pen (e.g. Mont Blanc, Waterman, etc.) is your favorite and why?

I interested in buying a new pen and want to know which pen is best. I currently own a Pelikan.|||by far and away my Mont Blanc pens they are wonderful and beautifully crafted. I got my first one as a gift from work then just added to the collection|||umm...why does it matter?|||I like Montblanc because they made it in sterling silver, vermeil, platinum, hematite, citrin, malachite, lapis lazuli, carbon steel, stainless steel, etc. Some have various jewels on the clip--red, blue, green stone etc. Special editions also come with a diamond top. I have all of them and keep changing everyday to go with my outfits.
