Wow!Berol Prismacolor for me, although they can be very temperamental. I took some to school once and some Grade 9 guys threw my pencil case across the room. Ever tried drawing with shattered lead? You can't sharpen the things.
For writing , I will use anything as long as it's an HB pencil, but for drawing, I am very picky.
The only pens I like are calligraphy pens, the flowery, romantic, old-fashioned ones. And I use those for word art more than for plain writing. And not for scribbling shopping lists, God, no!
