You've got to be kidding. Writing longhand was always a miserable experience for me no matter what technique or pen I used. Typing on a keyboard is so much faster and more fluent.
...and studies show, inferior for recall:

Learning to read I can see that handwriting directly relates but beyond that it seems like there must be more effective ways to engage with the material than just making the writing method more complex. I'd say the same about lectures; interacting with someone who understands the material can be quite valuable but spending a lot of time listening to the same thing that could be read can't be the most effective way to learn even if the complexity of the transmission does help some with memory. I hope this type of research goes beyond basic handwriting vs typing and looks into the effectiveness of additional ways of engaging with information.
For example, I like "don't guess" as a major principle of learning (per B.F. Skinner) to cultivate awareness of how reliable your memory is and avoid remembering incorrect answers as much as possible. The process of determining and looking up things that you aren't fairly certain about seems like something that could also engage wider brain activity and do so in a way that is more directly relevant to what you are learning.
