FaceBook vs Picasa test uploads

[mtbdudex]

Not exact scientific test, but because I took some moon shots with my new 70-200 f2.8 IS MkII lens, decided to compare:

-Aperture 3.1 used for PP
-Exact same image used for upload, just to different host site
-uploaded with std stock Apple Aperture Facebook uploader and Aperture Picasa 3rd party uploader (sized to 720 pix to match FB, used quality of 10 outta 12)

without "cheating" and looking at image source, which side is Picasa and which is facebook?

Image 1348 280mm (200mm + 1.4TC used), 1a

....vs 1b

Image 1350 200mm, 2a

same, without "cheating" and looking at image source, which side is Picasa and which is facebook?

.... vs 2b

I have some other thoughts, but will add later...also will compare Picasa to flickr, with some other more wider color range stuff.

In pics 1, 2 and 3 I think the top (A) versions look better. No idea whether that's Fb or Picasa.

3c is better than 3d.

4a is better than 4b. Just. Maybe.

I'm judging them on a visually-calibrated-a-couple-of-weeks-ago 11.6" MBA.
