I've used a variety of fountain pens -- Waterman, Diplomat, Parker, Schaeffer, LePine, and more. And the only pens I have ever found to be a complete delight to use are Pelikans.

I currently use a Pelikan 200 series with a 14K gold Richard Binder custom ground oblique italic bold nib. It writes the way I want a fountain pen to write, fills beautifully, works reliably.

If I have thought that if I were to buy another fountain pen, it would likely be a Pelikan with a fine gold nib, which would be more suited to everyday use in terms of the amount of ink used. But I suspect I would still gravitate to my bold italic nib for the "character" it brings to my handwriting.
