Which 4K format is better?

The higher frame rate is desired. Which means option 1. That being said, option 1 uses the 16:9 aspect ratio which is the common ratio used these days.

Not that I want to hijack your thread, I know the title says 3840x2160 or 4096x2160. In the past I have conducted tests between 2.7K and 4K. For me, this is just me, the sweet spot of the Mavic is at 2.7K 30 fps with a filter, it gives me cinematic look and awesome videos.
On this video I was facing the sun, hard to take pics and video facing the sun, around 1:30PM on a trip abroad. This vid looks awesome in our 4K TV at home, even tough it was shot at 2.7K.

One day I took the Mavic out to the park, programmed a 2 minutes Autopilot mission, ran the mission in 4K.
I landed the Mavic and ran that same mission at 2 more times during the day, lighting conditions vary as the hours go by.
A few days later, I ran that same mission 2 different times during the day at 2.7K 30 fps, as suggested by another thread in this forum.
Then I compared the results of the footage taken in 4K vs 2.7K in our 60' 4K TV at home. The video images of the Mavic moving at the speed of 12MPH ( as programmed in my Autopilot mission ) seemed smoother in 2.7K than the one in 4K, keep in mind that I was shooting at the same rate in 4K and 2.7K 30 fps, same filter, same light conditions.
The reason is because the video bitrate of the Mavic is 60 Mbps which is probably just enough for 4K @ 30fps or perhaps a bit tight. Now, this is not noticeable on a HD 1080p TV, so if you compare 2.7K and 4K the difference is not apparent.

I have a Phantom 4 Pro capable of shotting in H.264 and H.265. When I shoot 4K at 30 fps with the P4 Pro at 12 mph using a comparable filter the footage is much more smoother. That's because the bitrate of the P4 Pro is 100 Mpbs.

No issues at all.
I normally shoot at a fast fps ( 60 fps ) if I plan on creating slow motion effects during post. The Mavic can only shoot at 60fps in full HD or 1080P. In my P4 Pro I shoot at 2.7K 60 fps when there is fast movement. For example, last weekend I was shooting at a railroad loop mile and a half long train. During post I plan on creating slow motion effects in some parts of the video.
Alternatively 24 fps is more of a movie standard. When I want to create a cinematic look I shoot at 30 fps, like I did on the video posted above. However I was using an ND16 filter which makes 2 f stops, in order to compensate I had to adjust my shutter at double the frame rate, in this case 60.
In some parts of the video posted above, I slowed it down in some parts during post. For example when I launched and was gaining altitude I was going up very fast. When I slowed it down during post the video is not choppy. That's because the fps I was shooting at.
The image is best for me in 4k vs. 2.7k. Both are good, but 4k is sharper for me. Equally easy to edit in post as well. It might depend on your other camera settings though. I never underexpose.

2.7K is better than my HD TV, and I shot happily in 2.7 for quite a while. Then I got a 4K computer monitor, and I could clearly see the difference in the amount of detail and texture, so I went back to 4K. For now, anyway, I just love the sharpness, even more than the cinematic look.
