I only like to use specific pens....and will do just about anything to ensure that I don't have to use what I consider to be a substandard pen. That means that I often have at least two pens in my purse, another two in my briefcase, some by the bed, some at my desk....you get the picture. I also hide my pens. My good pens aren't for just anyone to pick up when they need one, I have some of those ones that I don't like for that!
The pens I like are extra fine. The finer the better. They have black ink and don't make blobs.
I like the sound of the fine point of the pen scratching across the crisp white paper.
A fountain pen would probably give me the ultimate point, but whenever I try one I usually get ink on my fingers.
My current favourite is made by Pilot. It isn't the finest point I've ever used, but it has the nicest writing point.
