If, for the average user, they can do what they want to do without the platform breaking and without having to look for their data, then in one measure, the new platform "works better".
It is also far less complex for non-technical users such as the elderly, technophobes, young children, etc. My ex's niece for example was able to use an iPad pretty competently at 18 months old.
Your usage pattern evidently is not representative of the average consumer.
All this is entirely subjective and depends on the user. iOS is not intended to be one platform to fit every usage scenario on the planet. If you need manual file management and other stuff iOS doesn't do, Apple sell Macs for that.
If apple wanted to build a device which does everything a Mac or PC does, they would have just built another Mac. That's not what iOS is about.
