I bought a Jinhao 85 when it was very recent (early corona days if I am not mistaken), and it was so good that I now I four of them in different colors, including one that I sanded down to paint myself to match my motorcycle (using the same paint). I love this pen and very much recommend it, it's very smooth, if a little (top) heavy for my taste, though nothing egregious. My oldest one (metallic blue with gold cap) has seen a lot of use, and for a while, became my main pen. I have never had an issue with it. The one thing that bothers me about it is that with the hooded nibs, the feed is glued in the section, so that limits the ink choices due to the inability to take it apart to clean it properly.
I am surprised that you were disappointed in Jinhao pens, at least recent ones, because I have 14 or 15 of them now, and not one of them has been a disappointment, though I know some of their older stuff is a little... dodgy to say the least. In contrast, Wing Sung and Hong Dian pens have never quite matched my expectations from reading online reviews.
There is also the Jinhao 911, lighter and slimmer, but same very smooth nibs. It feels a lot like writing with a pencil in terms of paper touch and feedback. I would also very much recommend this one, given the 2€ or so price point. Crazy good for the price, but does require extra care again, due to the hooded nib.
Do note that they both rely on (included) cartridge converters.
