The one major area where I think Android leads (at least stock Android, Nexus, Pixel) is text input. The voice typing on android is significantly more accurate than on iOS, and has been my biggest hurdle in getting used to iOS. I know few people find voice typing practical, but once you get used to it it makes pecking out words manually feel incredibly inefficient by comparison. Also the android keyboard swipe technology works very well, and I miss that a lot on iOS. I know you can technically install third-party keyboards, but they tend to not work very well due to iOS restrictions, plus then you completely lose access to voice typing and I'm not willing to give that up even if it's inferior on iOS. Since switching to iOS from android a year ago, I still type significantly slower and with many more typos than on android. If I could use android's keyboard and voice typing on iOS it would be the perfect device.
I do find it annoying that you can't use voice typing on 3rd party keyboards, but I use gboard for swipe typing and then will switch to the oem keyboard when voice typing. It's not perfect (because the kb switch button doesn't usually go the keyboard I want), but it does work ok.
FWIW, voice typing generally works well for me. Not sure why you're having so much trouble.
