I go back and forth on this so often it’s not even funny.
The two gel pens I like the most in general is:
- Signo DX 0.38mm
- Zebra Sarasa 0.4mm
I like writing with the DX more, but I find the Zebra to be more comfortable to write with, plus being capless makes it much quicker to get started.
At the moment my favorite is the Zebra, but that probably will change at least twice before the summer is over.
