I was more concerned with the difference between the cable holders presented by elpapiotr and the troughs. By aesthetics, I mean the laying of pipes over the plaster.
However, I am a staunch opponent of the lack of aesthetics understood as diagonal running, without respecting the needs of other installations. This is hell. The proposal from the photo of the Elpapiotr collection is not very aesthetic (wire harnesses are visible), but in my opinion it is perfectly acceptable above the suspended ceiling.
