Based on my experience with moving from a G3 -> G5 -> G6 -> G80 -> G9 (with GF5, GX80 and GX800 as extras), I think Panasonic's 1080p quality went a bit downhill with the G80 - it has more aliasing in 1080p than the G6, and in the GX80 it's on the soft side. The LX100 suffers badly from aliasing in 1080p as well.
Of the above list, the G6 is my favourite 1080p-max camera - but the G9 blows all of the above out of the water on 1080p quality (it's GH5 quality level).
If you want a really discreet, cheap, micro 4/3 cam with 4k and decent 1080p, try a GX800/850/GX880 with a stabilised pancake lens like the 12-32mm. 4k is limited to 5 minutes, 1080p to 20 minutes, no 'creative movie' mode (except by using 4k photo mode, which is 30p only), IBIS or viewfinder, but it's a really small, light, camera and doesn't suffer from the on-board audio IBIS noise problem which the GX80 and G80 have.
