I just switched back to Android as my main phone. My backup/second will be my iphone and I couldn't be happier. It was a four and a half year experiment with iOS.
I like the transit passes in Apple wallet but didn't like how Apple pay worked so I never paid for goods with it. Paying with Google wallet is much easier for me - I only have to present an unlocked phone and tap - no buttons to press and I can unlock with face, fingerprint or pattern. The dual e/SIM functionality started off well until I switched to iOS 26. After that, whenever I crossed a border, iOS would turn off one of my SIMs. I couldn't figure out what was happening for a while. I found out from apple support that was expected behaviour which was not present in iOS 18. I used almost all Google apps on the iPhone because I still have Android device. Regardless, I couldn't use Apple cloud because it won't back up photos from Android devices. Google happily backs up any device regardless of OS.
My number one reason for switching is the calendar app that I use,
aCalendar, it is the most intuitive app I've used. They don't make an iOS version but I tried to find a similar one and it seemed like all calendar apps on iOS work exactly the same - I know because I probably downloaded 50 calendar apps on iOS. Three taps to get anywhere whereas aCalendar is one swipe.
My new phone, a Xiaomi 17, can accept two physical SIMs or two eSIMs or one of each. The switch very smooth - Android copied my data, including 20k songs and downloaded the equivalent apps from the play store that were on my iPhone. The battery capacity is almost double that of iPhone 17 - I've already gotten three days of use from one charge.
