Pilot G2: The Budget Champion
The G2 is probably the most widely available Japanese gel pen in the world. It is the pen most people picture when they hear "gel pen." It writes smoothly. It feels comfortable. It costs under $3 per pen. The dye-based ink is not water-resistant, and the color range is limited to 8 basic colors. But for pure value and reliability, I think the G2 is hard to beat.
Best for: Budget-conscious writers, office use, students who need a pen they can replace anywhere. The 0.7 mm tip is the icon of this line. It is smooth, reliable, and predictable.
When to skip it: If you need water-resistant ink, archival quality, or a wide range of colors. The G2's dye-based ink fades over time and runs when wet. I learned that the hard way.
Uni-ball Signo DX: The Precision King
The Signo DX (UM-151) is my go-to for precision work. Its 0.28 mm needle-point tip writes lines so fine they look like technical pen work. The pigment-based ink is archival and water-resistant. The slim metal-clip barrel is elegant and professional. The trade-off? No retractable mechanism (it is a capped pen) and only 20 colors.
Best for: People with tiny handwriting, technical drawing, archival documents, and filling in Hobonichi grid squares. I have never found anything finer than the 0.28 mm Signo for precision.
When to skip it: If you want a retractable click pen, need more than 20 colors, or find slim barrels uncomfortable. The capped design means one more thing to keep track of.
Zebra Sarasa Clip: The Color Enthusiast's Choice
The Sarasa Clip offers the best balance of features for journaling and planning, in my opinion. The 40-plus color range (including the famous Vintage Colors) gives you serious creative flexibility. The pigment-based ink is water-resistant and archival. The spring-loaded clip is genuinely satisfying to use. The Nano variant pushes precision to 0.3 mm.
Best for: Journalers, planners, bullet journalers, and anyone who color-codes. The Vintage Colors set alone is worth buying a Sarasa for. I use them constantly.
When to skip it: If you need the absolute finest tip (get the Signo) or the cheapest possible pen (get the G2). The Sarasa is the best all-rounder but not the best in any single extreme. It is a jack of all trades.
Head-to-Head: Key Categories
Writing Smoothness
The G2 is the smoothest of the three at equivalent tip sizes. Its dye-based ink flows freely and feels buttery on most papers. The Signo has more feedback, especially the 0.28 mm. It gives a pencil-like feel that some people love and some do not. The Sarasa sits in between: smooth but with a hint of feedback.
Winner: Pilot G2 (smoothest overall)
Precision
The Signo DX wins this one easily. The 0.28 mm needle-point writes a finer line than either competitor. The Sarasa Nano (0.3 mm) comes close but is not quite as fine. The G2's 0.38 mm is the least precise of the three.
Winner: Uni-ball Signo DX
Color Range
The Sarasa Clip dominates with 40-plus standard colors plus limited editions. The Signo has 20 well-curated colors. The G2 is limited to 8. If you want to color-code or decorate your planner, the Sarasa is the obvious choice.
Winner: Zebra Sarasa Clip
Ink Durability
The Signo and Sarasa both use pigment-based ink that is water-resistant and archival. The G2's dye-based ink fades and runs. If your writing needs to last, skip the G2.
Tie: Signo and Sarasa
Final Verdict
There is no single winner here. The best pen depends on what you value most:
- Choose the Pilot G2 if you want the smoothest writing experience at the lowest price and do not need water resistance or many colors.
- Choose the Uni-ball Signo DX if precision and archival quality matter most. Especially with the 0.28 mm tip.
- Choose the Zebra Sarasa Clip if you want the best all-rounder with a huge color range, water-resistant ink, and a satisfying click mechanism.
