So, what are we talking about?
Isn't comparing two such different editors almost the same as comparing a gel pen and chalk, or oil (specifically for drawings) and acrylic (ideal for painting models) paints?
That was sarcasm... so please correct the post.
P.S. I've already had my fill of watercolors and gouache in school, although I can't deny that they are good and convenient.
...the advantage of watercolor is that it can be stored for a very long time without losing quality. Just add water.
P.P.S. I don't really like colored pencils; I prefer a simple, regular pencil. In my opinion, it's difficult to create a truly beautiful work of art with colored pencils.
But a work done in "black and white" is very good, because it's something completely different.
