Oh hell no. I used fountain pens, good ones, for nearly 20 years. They leak, blob all over the place, are difficult to refill, require cleaning, end up with servicing problems when you really need to write immediately. Also difficult to draw complex diagrams with. Absolute self inflicted pain and misery.

I use Muji gel pens now. None of those problems and you can take the cartridges back to them and they recycle them. And the pen bodies themselves last functionally forever.
