Even with the disadvantage....

That "unresolved" bird is a problem - LOL...

Actually, if you use the proper interpolation process you can also count the wire-meshes on top of the ladder and they are resolved as single wires. Here's a sample interpolated for an A0 sized print ( 44"x30").

Yes, the resolution is better on the 50D images, no argument there but the SD14 indeed resolves to the single pixel level.

many in this thread claim the SD14 to be able to resolve more details
despite of having lower resolution. it indeed resolves an impressive
amount of details for a 4.7 megapixel sensor and it compares very
well to the 50D, but by no means it can resolve more details than the
50D. i have looked at various parts of the image, but i have not
found a single part where the SD14 showed more details than the 50D
file.

you can clearly see that the 50D is able to resolve the ropes on the
very top much better, i can count the exact amount of wire-meshes on
the top of the ladder in the 50D file, in the SD14 file it is still
recognizable as wire mesh, but the are not resolved as single wires
anymore. and also look at the bird sitting on the top of the handrail
is just not resolved in the SD14 file anymore

i attached an image. the 50D file was converted with raw therapee and
sharpened very slightly to compensate for bayer interpolation. the
SD14 was converted with the latest ACR and not sharpened (i do not
have SPP). i didn't want to try any upscaling or downscaling as the
scaled image would always have a disadvantage over the unscaled one.
