4x looks bad.
2x looks really good laid down in the 4k 100mbps stream, but it's not as detailed at the standard 4k (more like very alias-free 1080).

Do you think 2x 4k looks better than normal ETC?

I do, cleaner by far.
I made some samples. http://www.dpreview.com/forums/post/54849358
1. 4k center crop
2. 4k 2x dig zoom downsampled to fullhd
3. ETC fullhd
4. best JPG center crop 1920x1080
5. RAW (ACR) center crop 1920x1080
I noticed that the sensor debayering ruins fine color detail even in RAW photo and levels the differences of different modes. GH4 4:2:0 4k video and ETC is very close to best camera JPG in 100% sensor readout. 4:4:4 RAW is sharper but not perfect.
If I use 4k/2x dig zoom I get a little sharper result that cropping 4k or using ETC.
I think that Samsung NX1 with 6.5k sensor debayering and downsampling is maybe far better than GH4 in 4k video. I think that even 100% RAW is worse in GH4. We will see.
