How about gel pen in calligraphy practice?

I am also a calligraphy lover. There are still some differences between hard pen calligraphy and brush calligraphy. In my opinion, the biggest difference is the change of ink color. The color of hard pen ink changes little, but there are two main differences between gel pen and pen. The first point: gel pens are smoother than pens, and will not break ink, which is more convenient, while pen writing will break ink, and children will press hard if they are not careful; The second point: the strokes written by the gel pen are not as powerful as those written by the pen, and the gel pen is vigorous and vigorous; Third, good ink does not fade, and gel pens fade. To sum up, my suggestion is that if you are a student, you should use a gel pen. You can't control the pen, so it's more important to develop good writing habits. If you are an adult, I suggest you use a pen to express your taste and style.
