I dunno, I had iPhone in my hand for app development, and I wanted to shoot it out of the cannon into the sun.
You have to understand the thinking process behind the UI, and it’s not ‘intuitive’ to everyone.
And I just couldn’t use it, it drove me crazy.
Not being able to do some things is the biggest blocker.
Sideloading for instance. Photos disappearing inside the Photos app and not being in files is also weird. It just felt like I was a moron who couldn’t handle my own files.
