A frame of 1080i video is composed of two 540-line fields.   And because
the fields come at a rate of 60 per second, the resulting frame rate is
30/sec.

When you say something like 540p30, that implies something like qHD,
which has half the horizontal and half the\ vertical resolution of full HD.

So saying "1080i30  is only 540p30" doesn't make sense to me.


> 720p60 is much superior with respect to motion


And 1080i is superior with respect to resolution.   Choose which is more
important to you.
