No.47
I've always liked using number 2 pencils, but I've always wondered, are there better or worse pencils out there? Could there be no.1 pencils, which would be shitty, or no.4 pencils which would be really great. I skipped 3 so illuminati fags wouldn't say any shit.

if you're an artist it matters

Well, from what I know, the "No." in pencils just deals with the shading/make up of the pencil lead? That's why standardized tests that use scantrons are taken with No. 2 pencils exclusively, because the machine may not pick up answers bubbled in with another kind of pencil lead.
Most of the ones out there are going to be No. 2 unless if you go to an art store that specifies. I've long since ditched wood pencils though and have been using mechanical pencils with .5 mm thickness. It's still No. 2 so I can use it on exams. Pic related is what I use.

In Australia, we use a different system for numbering our pencils. They go on a scale from 9H (Hard, very light shade of lead) to 9B (Black, basically charcoal.)
I'm not sure how pencil numbering like this works, but I don't like using any pencil harder than 2B, which is a pain, because the most common pencils are HB or 2B. I also don't like writing in anything Blacker than 4B.
I'd take a pen any day.
