I watch a lot of smartphone review videos on YouTube, and read quite some online as well (because I always research my next phone months in advance; sometimes the moment I’ve decided which one it’s going to be, I have to start over because new ones have entered the market…).
From what I have seen and read, for a grand, or in other words, a flagship phone, of one of the major brands, any camera system is top notch.
They all have their specialities, or gimmicks, but picture and video quality is very, very good.
What I also get from those reviews is to steer clear from OnePlus flagship phones since they seem to not have their camera game on point (yet).
Their latest team-up with Hasselblad seems to only be in the color science technologie (not so much in lens or build).
So, if you are invested in the Apple system you can without doubt go for their latest iteration of their iPhone.
