For most of us the best pen is the one that is functional and within reach when we need it. Everything else is just for fun or for show. It's nice to know what artists and people who regularly spend hours writing things out by hand think about specific brands/models, but I can't justify the expense of getting anything too fancy when I can go many many months without even touching a pen or a pencil and none of them are so advanced that they can make up for my bad handwriting.
And honestly some of the expensive pens don't write that well. I was given a Waterman pen and its ink cartridge was crap until I replaced it with a compatible cartridge from a cheap gel pen. And it still pretty much sits in a pen holder on my desk because the gel pens I like are lighter and cheap.
I mostly go with the Uniball Signos at this point. Though based on the article I should probably investigate more of the variants.
