No, revenue doesn’t necessarily equate to quality but devs are generally going to follow the money, you know, so they can actually make a living. There are endless examples of devs choosing to only develop for iOS because of this fact.
I’ve used both platforms continuously for about 12 years but I’ve generally used an iPhone for my daily driver for most of the duration, for numerous reasons. Right near the top of the list though is because many, if not most of my preferred third party apps either don’t even exist for Android, took years to finally come to the platform or simply aren’t as good as their iOS counterparts. So yes, from a user perspective it is a much better, quality experience.
