In my experience, the Merrill has better red discrimination than the Quattro, which - especially in Portrait color mode has mushy reds - it becomes difficult to discern individual hairs if they've been dyed red.

I go into depth about my experience with both here:

On the other hand, the Merrill can get blotchy magenta patches that are as likely to be noise as to be signal.

The fact that there is only one RAW converter for Foveon images ...

Only one, are you sure?

As to reds, my Merrills to date all have a low response to red (raw data), about -1 EV vs. the other two channels. There is a X2 multiplier somewhere in the conversion pipeline and that means more red noise or more red NR.

Check the reds here:

Depending on lighting, a patient's gums could look quite anemic when they ain't!

Not that we consider DPR's test shots to be the industry gold standard, eh? ...

Thanks a lot Ted. I always work under controlled conditions (ISO 100, Flash). Maybe, it may help somehow...
