You know, Miguel, something about this is profoundly funny to me that I'll explain in a minute - but I *actually* have something to add to my prior mumblings about the camera, and now that you detail your impressions, I think I dare to share it: Over the last couple of weeks, I tried to find anything, just about anything in the entire market that could replace it, and - there's virtually nothing, maybe except the Pen-F, but I find that camera pretty expensive for what it is (after all, it doesn't offer any decisive advantages over something like a E-M10 IV by now), and as you say, the GX9 works fantastically well with the 15mm. Not even
Fuji does anything superior - and that's been made clear by the arrival of the X-E4. All in all, apart from sort of cross-grading by picking up a E-M10 IV instead, there's nothing I could do. And that wouldn't tick the rangefinder style box ... So, my search ended with nothing to show. I *could* go for a
Sony A6100, but nah ... for all its virtues, it'd feel like a downgrade (I still own the A6000, I know that type of camera).
However, now for the more interesting - if somewhat predicatable - part: Another thing a SiJ does is make you very familiar with your chosen kit - this has been one of the key purposes of the format for a while now, and one many of us have exploited.
The funny thing is: Now that the challenge is drawing to a close, I'm mostly comfortable with the GX9 (again?) - the struggles and all the fighting with what the camera is were definitely worth it. Yes, the niggles remain, but they're just that: niggles.
That said, I'm not sure it'll stay with me long term - but since there's currently nothing to replace it with in a meaningful manner, I'll keep it for the foreseeable future.
The bottom line: We all know, but seldom consider, that
comparison is the death of appreciation. If you just use the GX9, it's a very competent, well built camera with a great set of features, period. And, as many of you have pointed out so accurately, of course(!) it can be enjoyed, and also tailored to one's tastes.
Enjoy the camera - I fully agree with what Andrew said in the "
GAS" thread: This is the best value in

right now,
at least if you buy new.
