Flight mode, you can try calling people out on an opinion, but that just marks you as closed minded. You can only "call out" on facts. The reality there is that the 777 is more economical and flexible. But on comfort, many people, though far from all, find the 777 seating in F and J more comfortable than the 380, despite the higher noise level. I certainly do. I can't say I noticed a lot of difference in Y, though the 380 lower deck ablutions are far more pleasant than the 777's. But my point about people saying the 777X cabin won't compete stands - no-one knows what that cabin will be like, so saying that you'd always prefer the 380 is illogical.
