Entirely unscientific judgement:
In my experience using the last Kodak Cmount full-frame (before Canon made a slightly more functional one), Kodak colours were better. Not only no slightly reddish cast, but clearer.
On the other hand, Kodaks various "styles" in their raw software made all manners of hidden tweaks, so some of the contrast and colour nuances may be credited to the software rather than to the sensor. The PS raw engine at the time did not extract the same results.
To make a proper comparison one would have to have the same colour palette exposed in the same light, which I have not done.
The camera body of the Kodak was terrible for manual focussing; dim viewfinder and not very high precision of matte-screen positioning. Close tripod based AME snaps came out unsharp.
As usual with large and partly fossilized companies, the distribution of official improved software stopped early so it was left to enthusiasts with inside information to keep supply lines open.
