I'd say it writes like an western EF / japanese F. Similar to my 3776 SF (without the soft nib of course).
I like mine very much. Smooth, reliable, does not dry out, works on most copy paper as well. It's also completely made out of metal and feels very well built. The only downside is the converter - it's a CON-40 style one and it's common knowledge that those kinda suck. And that taking the feed apart for cleaning is essentially not possible.
