For higher quality I have a Sigma 17-70C but on holiday I want a longer range zoom but still reasonably sharp (and want a metal mount).

I did buy a white box Nikon 18-140 a few years ago, it seemed to work OK on my Df but on my new D7500 it is soft at 18 and 50mm but sharp at 140mm.
On DXO it claims this is a good lens at all focal lenghts, but for me at the moment and on the ephotozine.com test shot at 18mm that does not appear to be true in the corners / short edges.

I have tried focus fine tune (it is about +5 now when set at 50mm) and limiting smallest aperture to F6.7 but I still do not like the 18mm and 50mm results much.

So shall I

a/ Buy another 18-140mm, in a gold box this time, as I have dropped my current 18-140mm once and hope the new one works more like the DXO review. Perhap Nikon have got better quality control over the years?

b/ Get a Sigma 18-200 C, they are cheap enough, it is an upto date design. As long as it is OK up to 105mm or 140mm I will be happy.

c/ Get a Nikon 18-200 Mk2, the DXO measurement data / graphs appear less good, but perhaps it takes sharp shots at 18mm and is well built?

or lastly

d/ Get a Nikon 18-300, the Mk2 (the F6.3 one) it seems to have good DXO data although it needs a fair bit of in camera distortion correction and has more tele than I need, it is a recent design.

Thank is advance Graham

I wanted more range so I went for the 18-300, which I've generally been very happy with. However, I'm a stickler for sharpness (especially at the 300mm end), and I was a bit dissatisfied with mine from about 225 to 300, and I complained to Nikon, who apparently agreed it could use a bit of adjustment. I sent it back to them and about a week later it was returned to me nice and sharp through the whole range. I don't really see much distortion or CA, if any. I'll add that 300mm is very useful and I like having it.  It's also a surprisingly compact, small and relatively lightweight lens.
