I have a Hakko FX888 (non-D, just a dial for setting temperatures), for general soldering work. I typically use it for bigger, simple stuff (soldering connectors onto 10AWG wire, etc).
But I have used it for a bit of circuit-board work, using a very-small tip. I was able to do what I needed on the boards, but I have no context for how well-suited it is to that, vs other tools.
I've been very happy with it, however, in the context of what I use it for. Maybe look at the tips available and see if they'd suit what you have in mind.
