The Coolscans I have don't know whether I shot the frame optimally or not. I also know what it can achieve and now it's consistenty over thousands of scans. Much more impressive to me are the results in color/contrast and all without drama.
Coolscans are impressive machines for 35mm and MF, but they are old, usually expensive, and have difficult service. They are very Pro machines... no doubt you have very good scanners.
Compared the Epson is relatively cheap, new, with warranty and service. It requires playing attention to focus (height), for optimal results you have to oversample in the scanning and optimizing in Ps, this is not painful today because we'll have (soon again) Ryzen 5950x + NVMe at 7,400MB/s... but still we require a proficient edition that anyway one should master for the hybrid.
The Epson, if proficiently operated, it is pretty decent for 35mm, totally capable for MF, and it shines like the sun for LF. The Nikon only makes rolls but my Epson scans 8X10" with more quality than I will never need... Still with the Epson a clumsy user will get a botched job after the other, but anyway he would not go much farther with the Nikon. It is the Comanche guy, not the arrow.
