Whether it is better to use 1.0 or 2.0 for creating art depends on the actual use demand and personal preference. The following is my analysis and comparison of these two pen tip sizes:

1. Tip size: The 1.0 and 2.0 of the gold paint pen refer to the tip size, that is, the diameter of the tip. The pen tip of 2.0 is relatively thick, and the lines drawn are relatively rough and full of color. 1.0 has a thinner pen tip, which can draw more detailed lines and screen details.

2. Picture effect: If you want to draw a rough and bold effect, or do some decorative painting, then using a 2.0 pen tip may be more suitable for you. If you are looking for detailed picture effects, or need to complete some details, then the pen tip of 1.0 may be a better choice.

3. Usage scene: In different usage scenes, different sizes of pen tips may have different effects. If you create on canvas, drawing paper and other large-size pictures, you may need to use a 2.0 pen tip for large-area coloring or finishing; On the small screen, the pen tip of 1.0 can better show details and fine lines.

Generally speaking, whether you use 1.0 or 2.0 gold paint pen, you can play the role of artistic creation. What size pen tip you choose depends on your own needs and personal preferences. I hope this information can help you!
