even simpler ...

Second: let's put it simpler: mum and Pop WILL find differences in IQ on their 7 x 5 prints.

This was the whole point of my wannabe technical tirade. EXR is not benefitial for pixel peepers, but people who don't want their gray hair have yellow/blue stains on it when photographen in really low light (and high ISO) and subsequently printed 7x5. This is where EXR really helps a lot.

I've proven time and again (counter-tirades notwithstanding) that there is a subtle and increasing difference between M size and L size. The L sized images always lose in the long run. The M size images retain better dimensionality and edge definition longer as ISO rises ... and as you pointed out, they resist chroma blotching much better. They also resist grain better.

So ... the differences are sometimes subtle, as ranted pointed out by Stephen. But your visceral reactions are subtle as well. You react to images without thinking about it (until later, when you might think about it. :-)) So improving subtle things like how edges are rendered and how texture and surfaces look (i.e. dimensionality) has a positive benefit. Reducing visible blotching has a very positive benefit.

And when we're taking about 5x7 prints, the resolution issues vanish completely. 8Mp is enough to make a good quality print right up to 13x19 (see: http://www.bythom.com/printsizes.htm ) so there is quite literally no reason to take the risk of using L mode, ever, for 99% of shooters ...
