I'm studying this recently ~ I suggest going to a big store and actually trying to write down my personal opinion. If I write everyday, it may be more suitable for Vidic ~ Reason: In terms of the thickness of the pen tip and the steel tip, Paczal, Yunfeng, Shiya and Vidic are more elegant or harmonious. Parker's common pen tip is F, which is usually thick and suitable for signing or filling out reimbursement forms. Vidic's common F pen tip is thinner. It is more suitable for daily single-line paper climbing lattice such as gambol, and the width is similar to hero's daily pen, which is about 0.6 to 0.7 ballpoint pen or gel pen. The Golden Tip Zall is thinner than the Steel Tip Zall, but it still feels a little thicker than the Vidivian Steel Tip F, so it is recommended to try to write it in the store before buying it to see if the thickness is appropriate, so as to avoid problems, just play Pickville and Yunfeng. Zall (both gold and steel tips have been used) is elegant, harmonious and elegant. Personally, it seems that the low-end (steel tip) of Vitiwen is a little better than Parker's.
