How is OnePlus 13/13R compared to Samsung/iPhone?

Hi there!

I'm looking for people's experiences using a OnePlus 13 or 13R. I'm particularly interested in how it compares to recent Samsung devices, because I think Samsung One UI currently offers the best UX on Android. To a lesser degree, I'm also interested in how it compares to an iPhone.

I'm not interested in games performance. I care about reliability first and foremost, then about battery life. Camera performance and smoothness come later.

If you've used a OnePlus 13/13R and a recent Samsung or iPhone, please leave me your comments. I'm interested to know your experience, no matter which of these phones you prefer at the end of the day.

Thanks a lot!
