1080 vs cropped 4k

[Richard-Inspire]

does anyone have a comparison between what the 1080p footage looks like compared with cropped 4k footage to an equivalent pixel count?

Reason for asking is that I wouldn't normally bother with 4k, as I just don't believe it's worth it (not trolling, just a personal opinion that you need significantly better glass and sensor for 4k to be worth it) - BUT, if the 4k video resolution allows for a reasonable amount of cropping before quality gets too low, then I'm all for it.

Yesterday I tried using 4K video as a source for a 1080 project. The main reason for this was so that I could 'zoom' in down to a 1080 picture and get a closer image than the local aviation rules allow. I was very disappointed. The cropped image was very inferior to the native 1080 on my Inspire 1 with the X3 camera. Has anyone tried doing this with an X5?

One is 4k other is 1080p cropped...oh yeah and it's not sharpened...or color corrected and I was using Renaats 1st round filters...which have color issues

Shoot in 4K to capture the best video, most data then edit and format for your audience .. usually in 1080p

(note: writing 1080p output from a 4K source is not a 'crop' in this example)
