To compare between ballpoint pens and rollerball pens, which is the most comprehensive pen model, there is probably no exact answer 100%. Each version is favored by different users, different needs. However, both have in common that they are made from high-quality materials with legendary pen designs that are not overshadowed by time.
Talking about the trackball version, these will be convenient pens, quick to use without too many operations, just one turn and you can sign/write. Using a dry gel pen refill, even if you forget to retract the tip, the pen will still limit ink from spreading on your shirt, at the same time, this is also the type of ink that can be used for all types of documents.
For fountain pens, you will see that these pens are designed with a cap that covers the nib cluster, both to increase the aesthetics and to help preserve the ink from leaking or drying out. The nib will also be more beautiful than a rollerball, but in return, if you forget to close the cap, you may ruin a shirt!
