The best case I can make is that for most everyday uses, watt-hours are useful for estimating power consumption e.g. if I have a 100W light and I leave it on for 8 hours a day, that’s 800 watt hours on my electricity bill. Simple. Sure you can do the same thing with joules but it’s a little bit more unit conversion and I don’t think it makes it any easier to intuit how a device will impact my electric bill.
With all that said it rubs me the wrong way too. Same with VA vs W for AC circuits. I get why you need apparent vs actual loads, w/e, but that naming convention just bugs me. just call it a loss factor or something.
