BOTH
I use whichever one I feel like using.
I try to have a mix of vintage and somewhat newer pens inked up.
However, when it comes to cleaning out the pen, a modern cartridge/converter pen wins hands down. That is the only one that I can use a bulb syringe on, to force clean the feed, with LOTS of water. And the cartridge or converter is easy to clean.
