Weird, I've decorated my house on PS4 just fine with a controller. The only annoying part I can think of is selecting specific placed furnitures that you want to move/spin because you have to go down the list of placed furnitures 1 by 1 using X on each until the one you want to select is highlighted, specially annoying when you have like 100 of the same partitions placed. But other than that, it seems fine to me and I've managed to clip stuff without problems. O.o
