I've had the Staedtler Noris Jumboand love it for drawing. I just purchased the Staedtler Mars Lumograph Jumbo and wanted to test the differences using the pencils in Atelier.

Here's a photo of the results.

The columns are:

L - Light pressure lines

H - Hard pressure lines

T - Tilt/attempting to shade lightly

X - Crosshatching with various pressure

The Mars is soft feeling like the Noris, which I like. But I found that I could not get as light a pressure /line with the Mars as I could with the Noris. You can see that in the photo too.

I think I'll stick with the Noris for art, but will add the Mars to the rotation for note taking.
