There are many comparisons like this but always only in terms of detail. GH4 has twice amount of resolution so it is not a suprise that it better resolves small details. In such comparisons clips ale always graded to match themselves, (usually mark iii is pulled down to match gh4 colors) I am waiting when somebody makes a comparison of grading abilities of the two (and of course give the title "which is better" ;). Remember that the biggest advantage of raw video is not detail resolving but almost complete control over your footage. White balance which you can change on the fly, huge shadow/highlight recovery abilities, no banding even after heavy grading, NO compression artifacts at all. And people always shows STATIC shots. Show us some fast moving scenes. I would like to see some glidecam walking shots, Ive seen some moving scenes out from GH4 and they are decent at most. When camera is moving and there is motion blur, most of the details are not visible and motion artifacts/macroblocking comes really visible
like here (see the boat scene)
I dont know if you saw this, this is a very nice explanation
Mark iii with Magic Lantern and GH4 are both great cameras and i would like to have both. When i see next "which is better" video focused only on sharpeness and nothing more it is not fair at all. And remember that ML gives optional 3x crop without any binning, there is also fully usable 2,5K raw if somebody need more details in certain scenes.

ML RAW for an archival setup is total madness. The A7s will come out in June-July and is way better than the 5D mkii for video.
You dont need to archive raw files now, you could just keep high quality 10bit DNxHD or prores rendered with excellent cinelog profile for later grading.

This comparison and most of them are made of entirely static shots. In this case clarity and detail are amazing, 4k outperforms 5d's 1080 in terms of detail and its obvious. Things are little different when camera is moving (for example in glidecam shots). Add even tiny amount of motion blur and its hard to tell the difference, footage looks decent at most, compression artifacts in gh4 footage becomes much more visible either. This is where 14 bit raw color depth and highlight/shadow recovery ability gives better overall image quality and nicer feel.

Great review Andrew, one thing is missing though. Could you please do a rolling shutter test a7s full frame (could be with s-log for better image) vs 5d mark iii ML raw? The rolling shutter seems to be a huge concern for many people. It doesnt have to be an extreme waving form side to side, just some normal, little bit shaky handheld footage. Thanks
