DSLR and P&S Smackdown

This might be fun. Yesterday, I took two pictures. One with a Canon SD890IS
and a second with a Nikon D300 with the Nikon 18-200 mm zoom. I've posted them
at:

http://www.classtech.com/DSLR_PS_Smackdown/

The question is "Which camera took which picture?" and "Why do you think so?"
They are labeled "A" and "B" for purposes of discussion.

I'll post the answer when the discussion dies down.

The picture isn't much, just a shot of a Mc Mansion being built. But there is
lots of detail and texture.

Methodology comments:
I took the two pictures from the same spot within a few seconds of each other. I
took the jpegs straight from the camera and loaded them into Photoshop. I
cropped (not resized) the DSLR picture to match the size of the P&S picture.
Then I copied each into a new image to eliminate the EXIF data. Finally, I
saved each as a jpeg at the lowest compression available.

A is the DSLR, in my opinion, because of the dust spots that are visible on
the image.

I'll go with A as the DSLR. It seems to show a little less DOF in the
foreground leaves and B is more heavily sharpened with more blown
highlights, a lot of noise in the blown aqua sky and a bunch more
chromatic aberration. I sharpened both in irfanview to emphasize
differences, then raise the gamma & contrast to 2 and the differences
are real obvious.

Caveats: B is exposed a little brighter which could explain the blowouts
(but ought to reduce noise) and sharpened more which could explain the
leaves looking a tad sharper. The 18-200 is not the best lens so could
conceivably be B with the chromatic aberration problems. Depending on
the settings the DSLR jpeg might be over-sharpened or too contrasty.

I'll post the answer when the discussion dies down.

I'll go with B=Nikon because the sky has Nikon's characteristically tending
to washout but never quite does look about it plus a cooler look to the
whole image, another trait. I could easily be wrong though, as user
settings can swing it either way.

I'd say that B is the DSLR.
When I blow the pix up 500% in Photoshop, B shows finer detail in a
window ledge. However, that COULD be due to more native sharpening
typical in P&S cameras.
I think the important point here is that experienced observers find it
VERY difficult to see significant differences in images from a $325 P&S
and a top notch DSLR selling for 5X as much.

At that tiny size, yes. I'd guess A, fwiw, not much!

Well, I'd like to own whichever took "B". "A" appears to be in soft
focus, and looks jaundiced...

I figured A was the P&S, without looking at the B moderate-size
version. I reckoned it was easier to zero-out the dSLR's in-camera
processing (or it was less likely to be overboard initially), and the
P&S was extensively processed before Mr Johnson got to it.

Is there any avid photographer who has a high end P&S and a dSLR who has not
compared essentially identical images from the two cameras?
I began doing this with my late lamented Sony 828 and my still used Nikon
D70 and later D80. The dSLRs were not always obviously better.
Currently I pit a Panasonic FZ18 against the dSLRs. Alas, the Panasonic is
such a noisy beast, even raw at ISO 100, that it is usually not difficult to
tell which camera made which image.
However on a hot day lugging the FZ18 around sure beats hauling around an
SUV sized dSLR and 18-200VR Nikon zoom.
