It's a super lens and when I tested mine against my Canon 70-200 f4 L IS on my 6d ii the Fuji lens was on par and that Canon was the sharpest telephoto zoom lens I'd ever owned.
You may find it gets a tad soft from 140-200mm however I find it still perfectly sharp. I think a lot of people who complain it's soft at that range are just spoiled because the 55-140 range is so darn good!
I know what you mean but it's sharp enough for my liking.
200mm f/4.8 and straight off the camera, no processing:
