@Jon I tested Lightroom, Photoshop and DXO. Of those, DXO seems to deliver, hands down, the best results with the least amount of work. Both Lightroom and Photoshop perform some sharpening that seems to introduce a decent amount of noise in the results. I spent a lot of time testing various settings and the first results from DXO were better than anything from either of those.
I also found that with my camera array, in cases where I had shutter shadow, Photoshop and Lightroom produced different results for those images from the rest in the set. The results from DX0 were very consistent. FWIW
