3's grip looks the most comfy

Preference aside, I've found that most others use the 0.5mm and that that means my pens usually find their way back to me when borrowed. I generally like the way the increased flow feels and don't experience a difference in control vs the finer tip. That said, the 1.0mm is crazy and feels like I am trying to paint, so I definitely get how others that prefer the finer tip might feel about my preference.
