We're talking apples* and oranges. I say that OnePlus has put up their prices and you say 'sure, but look how expensive every other phone is'. I say that OnePlus have moved on from being able to call themselves flagship killers because of the price and you again say 'look at how much you get compared to the most expensive Apple product with some added storage options.'
As a side issue, that iPhone 11 will be fully supported in 5 years and will be running the latest version of the OS without lag or stutter and it'll still be worth a few quid second hand. At that point, you could argue the iPhone 11 gave you a lot more for your money.
* no pun intended.
