I am always and forever on the quest for better pens for writing and drawing. I'll tell y'all what I like to use now, what I've tried and kinda liked, and what I'm just not into. Then you will unleash your inky obsessions upon me, and I will have great new pens to try.
In order to steer the recommendations, my current "HELL YES" drawing pens are...
Pilot Bravo marker pen - Ohmygoodgod, I would buy EVERY SIZE of this pen and use nothing else… if only they made it in any size other than the one they make. (Which is pretty bold, slightly larger than an .08.) Super smooth, not smudgy, nice looking barrel. Plastic tip is sturdy.
Pilot Fineliner - The closest thing I've found to a finer-point Bravo. Don't love the "retro rocket ship" barrel shape, but I can deal.
Sakura Micron Pigma series - The .005 and .01 have been my usual for detail-drawing. The tips wear out faster than I'd like, though, and I'm starting to lean more on…
Pilot G-TEC series - superfine rollerballs with exceptional smoothness. Barrel could be more comfortable to hold, and I kinda hate the cap… but the performance makes it worthwhile. I like the .04 size for writing, too.
For everyday writing, I like…
Pilot Precise V5-RT retractable rollerball - Great action all around, acceptable look. This is my go-to writing pen, and I have them lying around everywhere; at home, at work, and in my pockets.
Zebra BP F-301 retractable ballpoint - I love the weight, feel, and classic look of the stainless steel body. The pocket clip is solid, and the spring action is terrific. Its actual writing performance isn't any better than any other ballpoint, but man… if I could shove ALL other pens' ink barrels and tips in a Zebra body, I would.
And I'm still a sucker for the old Bic Crystal ballpoint stick pen.
Some others that I've tried that I like okay…
Pilot Razor Point - Feels almost like Pilot's version of a Micron to me.
Sanford Uni-Ball Micro / Onyx / Vision Elite - I used these for a while for both writing and drawing, but they get kinda scratchy.
Staedtler pens in general - Pretty good, but for almost every pen they make, Pilot makes something similar that I like better.
Faber-Castell Pitt Artist Pens - fine, but nothing special.
And things that are just not for me...
Fountain (or fountain-style) pens.
Fat "Dr. Grip" pens.
Cartridge pens like Rapidograph (that I know I just will not maintain).
Anything that one would describe as "executive", or that comes in its own case.
Thanks to these three posts
on AskMeFi from 2005, (and discussions in a few other forums,) I already have a short to-try list going: the Pilot G2 and Zebra Sarasa for writing; Stabilo, Niji Stylist, Pelikan Techno Liners, and Copic Multiliner for drawing.
But I want more! More, I say! Fellow pen obsessives: GO!
