flatbed for color negative scanning

I'm looking into A3 reflective flatbed scanning options
(screen cezanne, fuji lanovia, kodak iqsmart, eversmart supreme etc),
however I was curious in experiences with scanning color negs with these as well.

Does any of the possible software:
- Colorkit,
- oXYgen,
- Colourgenius
give beautiful results regarding colors.
closer to Pakon, Frontier, Noritsu colors?

I scan lots of color negs with an iqsmart 2. So far no complaint about color but I do nothing but the basics in oXYgen. Just set endpoints and scan. Everything else in Photoshop.
