This is all fascinating! I have been using Faber-Castell 1320 HB for my D&D games, and they've been great. They're not exactly rich in colour, but a single sharpen is more than enough for a whole day's session. I don't have anything to compare them to though.

I'm going to have to research what you mean by grades.

You mentioned preferring mechanical, but didn't say what kind you like. I've always heard that Rotring's are the grail there, but never looked into it.

If you have never tried using different hardness grades, just find an art supply shop with a display of drawing pencils and try a little scribble with each grade. Note that since every brand is a bit different, you can't use your experience with one to exactly predict the quality of another, even more so when comparing wood-cased with mechanical pencil leads.

As for MPs, if you really get into it, you could end up with many different ones for different situations, sort of like with paint brushes or golf clubs. Even cheap ones can be comfortable and durable. Some people like the Rotring because of the heft, but they are a bit sharp and the weight can get tiring, rather like with using metal polyhedral dice.
