I've tested many Android tablets over the years and all the iPads from 2017 onwards.
There are un-optimised apps on Android and on iPadOS? FB, Instagram, Twitter just to name a few. FYI, you have the choice to not blow up un-optimised apps to full-screen on Android.
Someone mentioned the user experience is bad. To use apps, you just tap the icon and use it. Yeah, I'm simplifying things here. But the main this is I've never felt I was held back by Android OS or the UI companies put on top of Android.
Samsung eco-system is pretty good. Huawei has built their eco-system really fast in the last 2 years. Xiaomi needs a lot more work.
The thing with Android is there's limitless tablets options and you can choose based on price, design or features.
As an artist and graphic designer, the main reason to get iPad is the graphic design apps are just much better. E.g. Affinity Designer, Adobe Illustrator, Vectornator, Amandine.
iPad has video editing apps, cool. I edit many videos and I won't want to edit videos on iPads due to productivity concerns. But hey, if you edit videos on iPads and it works for you, great.
I've tested so many tablets that I don't really care what I use as long as I can get my job done. And I find it very difficult to do graphic design on Android tablets which is my main gripe about Android OS.
