That word “ecosystem”, it’s not just another random feature of IOS, it is the core. I left Android about 7 years ago so I’m not sure if there’s any such thing as an ecosystem but in IOS that is biggest reason, of course there are individual bragging cool features for both platforms but don’t underestimate the ecosystem. My daughter fell of her bike and immediately Apple Watch alerts me and calls the ambulance as well, fortunately it wasn’t a severe fall. Stuff like that is priceless, I can copy something on my phone and just paste it on my laptop, there are probably equally cool stuff on Android, but the ability for IOS devices to interact seamlessly is what makes the difference imo
