I just got a HTC One M9. Since both the M9 and the Icon have a 20MP cameras, I decided to compare the two.
I set both to RAW capture and took these pics from the same distance and under the same lighting conditions. I open both up in Adobe Camera RAW and saved them as is without any adjustments. The one thing I noticed is that the M9 doesn't save a 5MP version. Both the JPG and DNG versions are full resolution. Anyway, here are the two different images.
Lumia Icon:
HTC One M9
The M9's looks closer to what I saw and seems to be a bit warmer. The M9's also seems to be a bit better in saturation. Performance wise, the Icon's camera is significantly faster when compared to the M9. I haven't tried video yet. Both cameras can do 4K video capture.
