Apple

At this point it's basically only personal preference.

There were times when iPhones were objectively better than most androids. That was rather in the earlier days.

IMO since 2017/2018 Androids which are in the same price range as iPhones offer the same or more features while also being of good build quality and software quality.

Regarding features; Androids tend to offer more features, but in 99% these are rather experimental and are often not even transferred to the successor.

The only consistent feature I can think of is personalization, and googles AI progress with their current Pixels.

One could argue that Androids are a tad more interesting, since you can do so much stuff through 3rd party apps or by default, or you have crazy camera setups and SPens and whatnot, but in the end it's not an advantage if you won't use those features or if they are messy.

So yeah, if you want an S-Pen or a crazy 200mp 10x space zoom Setup you obviously won't go for iPhone.

I personally prefer the simplicity and mature design language of iPhones.

But If a future Android offers a feature I deperately want I'd switch again. And also switch back. I don't lock myself to a brand.
