Different people like different writing instruments. Some like smooth pens, while others like pens with a little bit more resistance.
I like smooth nibs. The less the friction the better it is.
I do in general also prefer broader nibs. I think they look better on the page. And I just gravitate against writing instruments that feels good to be, and look good one the page. In other words, the more ink on the page the better. Some people like a lot of ink on the page, while others don’t.
When it comes down to ink capacity I have some very strong opinions. I think pens with larger ink capacity always are more useful than those with a lower one. This is because if you write a lot with pens, you either need to have a piston filler, refill them all the time or have a lot of them. Back when I was a full time student, I loved my Lamy 2000. I filled it in the morning and I never – not once – ran out of ink during a single day. The story is another with the Pilot Metropolitan. That one never lasted more than a couple of hours.
If I’m just writing a few lines here or there then I often use my Falcon or VP. But I always go for either my Lamy 2000 or ink up one of my TWSBI Eco’s if I’m going to write a lot. Or if I need a lot of ink capacity away from home and don’t want to bring a bottle of ink.
