I use a Zebra 402 0.7mm

Compared to kids these days, I used to write a lot in high school and college and the only memorable pen in terms of comfort, color and thickness that stood out was the Zebra. I write much less now and mostly use it for quick notes and back of envelope schematics.

My #2 choice would be a Parker Jotter ballpoint, which is quite similar in form and weight.

I absolutely hate gelpoints and any other sort of gel pens.
