Quite a bit, just got back from a flight on Friday.
For me the question is immersion versus isolation. For example, noise cancelling is great as it cuts all of the engine drone and white noise associated with air travel that can intrude on whatever you're trying to listen to so for those sounds it's great isolation and really good at immersion. However where ANC fails is voices, babies crying, glasses clinking, silverware and all the other higher frequency, variable noise: the QC35s and MDR1000Xs let those sounds right in so in that case it's neither isolating nor immersive.
The P7Ws have good passive isolation but it's not comparable to an ANC set or even close for engine drone but it's better than ANC sets for babies crying but that's not to say it's much better.
This is where immersion comes in. For me, because the P7Ws sound so much better than any ANC set, if you're running any kind of decent volume, everything else just kind of melts away and you get lost in the sound. That means pretty much all outside sounds are either not heard or not noticed so, for me, they're now my go-to set for air travel.
It's going to be an individual preference thing, but after 4 years of using ANC I'm now on the P7Ws exclusively for air travel.
