I wish I could switch to the iPhone, and I've tried several times. The hardware is excellent. But these are my deal-breakers that keep me on Android (I've only ever had Google Nexus / Pixel phones): - Lastpass or any other password manager on iPhone is a joke, requiring multiple convoluted steps and using the "share" menu in the browser because of the Apple lock-down. Lastpass on Android? Click the password field in…
I use 1Password and filling out passwords on iOS is actually better in Safari than it was on Android Chrome. It's not that convoluted at all: share button, hit 1Password, tap the site entry on my password list. Done. By contrast, I had all kinds of issues on Android with the 1Password button not appearing sometimes, or failing at other times (it was an accessibility hack, so I suspect they were doing the best they could)
I also found the Google apps to be of comparable quality. Maps, Play Music and Inbox are all but identical. I'm also quite content to diversify my data a little and depend on Google less. I even switched the iOS default search engine to DuckDuckGo.
And as a last point: Google Photos is available on iOS. And works fantastically.
