It's implied that both Airbnb and hotel must be available to make a comparison. When that's the case most of the time hotels are better.
That being said, if there are no hotels available of course any other alternative would be better.
If you've a large family with multiple children yes, Airbnb may be better
The example I gave is explicitly where they are both available. A hotel near my extended family, or a detached house from Airbnb that has bedrooms for my kids and a full kitchen for a similar price as two rooms in that hotel.
> most of the time hotels are better
That which can be claimed without evidence can be dismissed without evidence.
> a large family with multiple children
I'd posit it's better with any amount of children, especially if they're under, say, 5 years old.
