It is correct that many scanners cannot 'duplicate' otherwise good transparencies and negatives due to one limitation or another. We have seen how even recently Kodak improved the scannability of their films and advertized the fact.
This depends on a number of factors such as the support itself which can contain materials deleterious to scanning. One example is the gray carbon that Kodak uses in some supports as an antistat. It could cause problem. Other Kodak films have 'retouching' matte on the back which could cause a problem. IDK, but I can use up all of my fingers listing impediments to a good scan from a good original from either Kodak or Fuji.
I would say personally from analysis and talking to quite a few pros, that the best that I know use Kodak negative films and Fuji reversal films. Both companies are actively engaged in improving their deficient areas.
As for complaints or problems. How come no one ever 'rants' that Fuji is not posting here or advertizing here?? How come no one ever really speaks to the BIG difference in the quality of the Kodak and Fuji databases on their respective web sites. We have seen lately though that Fuji's database lacks certain information whereas Kodak's does not and includes much more than anyone elses.
Therefore, I would say (in spite of my EK bias) that Ilford wins B&W, Kodak wins negative color, Fuji wins reversal color, Kodak wins web site quality.
Kodak and Fuji lose representation on APUG and PN. Kodak and Fuji win advertizing on PN.
You see, from my POV, there is no clear winner and it is certainly divisive to keep this up! Everyone should use what works for them!

Ron,
You sum up many of my observations perfectly.
One of the reasons why I said I'm coming to love Portra as color neg film is its scannability.
I don't want to stray too far into "forbidden territory" but in one of my own threads here not too long ago I noted that I was pleasantly "surprised" that after scanning a roll of 135 Portra negs (I used my Nikon 5000D) and did a quick "Auto Adjust" in PS - there was not adjustment at all! [(there was a url link here which no longer exists)
This is as opposed to using other films, both negs and chromes, where there is a definite "lightening" and, I suspect "color shift".
Having given up on Kodachrome (because there is a time when you just have to "move on") I haven't tried any of Kodak's newer 'chromes so cannot opine on them. But I do very much like Fuji Velvia (both the 50 and even the much maligned 100).
But even Velvia scans, as well as those of other color negs such as Superia or Kodak's equivalent will "shift" when you use the PS "Auto Adjust". Then, you have to decide if you "agree" with PS! [DISCLAIMER: I never post "adjusted" pics to The Gallery here!]
But the fact is, as Tim first noted, the color shift is not a function of the film - it's a function of the scanner. And this is why the OP would have had an interesting item of discussion on Hybrid but is advancing an irrelevant point here.
Oh, yes JD, I doubt we'd ever be able to host a Kodak rep here. Would more likely turn into a roast.
Although there is a way it could be done - via a "screened" Q&A - but that would really rankle some people.
