Actually even I've been considering an iPhone since the last few days. Pertinent software issues on my OnePlus has forced me to look down that road.
I've very recently gotten ~$850 worth prize card from my company for participating in an hackathon, which I could use globally to buy anything. So I've been thinking of redeeming this prize card at an Apple Store in the US, once the Covid related restrictions ease.
From what I've seen iOS is very very restrictive, OS level as well as payments level. A majority of apps do not allow in app subscriptions because of app Store restrictions. That is really worrying me. Although I do have a laptop to take care of the subscriptions part, but not everytime will I have a laptop. If my next phone after the iPhone were to be an Android, there's no way that subscription for an app from the app Store can be cancelled unless you actually have an Apple device.
Another downside is the price. $999 for the Pro variant. In September I'm really hoping that this price goes down, but I'm actually ready to wait out until next year September because I think I can install custom rom to mitigate software problems.
Everything just works on the iPhone. You get the same software experience across the range of iPhone models, unlike Android. This is the biggest reason why I'm considering iPhone.
If you're ready to wait out the next 2 months, the price of 11 Pro may go down. Else you can go for the 11.
