I will say, even with the Chinese ROM, I feel like I can use so much more software and have better access to my device than my old iPhone. For one, I can connect the USB with my computer and share files quickly, and F-Droid has so many cool apps that work, and in many cases look, awesome! Being able to use different default apps, use a different launcher, and customise the icons easily with an icon pack (Apple’s sorry excuse for icon theming isn’t all that great, all you get is either a glassy colour or glassy glass)
