Also a big fan of the Uniball, perviously was using Signo DXs, but have switched over to the Uniball One. I think that slightly thicker barrel helps with my handwriting. Also love the wire pocket clip.

I do like the Rotring pencils over the pens, but still prefer Uni as I feel less bad about losing a Uni Kuru as it is cheaper and still has knurled grip. Also has a fun rotating lead.

I've picked up each color of the new metal body Kuru Toga, and they are an extra level of extravagance on an already perfect pencil: https://www.jetpens.com/Uni-Kuru-Toga-Metal-Mechanical-Penci...
Pigma Microns and Uniball One are my go-to pens. Previously it was Signo DXs as well. I think I prefer the barrel of the DX, but the wire clip and general appearance of the Uniball sold me.
Those are very nice! I like the Uni Jetstream RT: https://www.jetpens.com/Uni-ball-Jetstream-RT-Ballpoint-Pen-...
It feels really nice to write with. I also have a Kuru Toga I picked up at a neat little stationery store on vacation, but I was reminded when I got home that I don't care for writing with pencils. Should that change, there it is waiting for me.
