They were even better when they were first released, in the eighties if I remember correctly. I think they miss the top lists because they've been superseded by fancier Uni-ball pens.
Those used to be my favorites, but the quality seemed to have gone downhill and they started to come with less ink in them. I moved on to the Uni-Ball Deluxe, but then it seemed like the same thing happened. So I got a budget fountain pen - nobody can retroactively shaft me on ink quantity or build quality.
Sakura figma series glide well, and are what I settled upon. But I needed to go down a few steps of tip size to 0.2mm to achieve the same line width as my previous favourite of pilot v5 hi-techpoint.
