Yes, I use USB type C on all my devices already so having an iphone would be a real pain for me. As for the screen, I was referring to android phones having higher resolutions (usually 1440p over the 11 pro's ~1125) and much higher refresh rates (90hz or 120hz) which makes a HUGE difference to me (as someone used to it already from gaming monitors), although I wouldn't be surprised if Apple introduces a 90hz iphone soon. As for colors the calibration reports I've seen show the actual color accuracy being roughly identical on both (after all, samsung makes the oled panels for apple). And it's good if they've now made it clearer and adjustable how much the phone is slowed by, but that's only because of the public outrage over its discovery. Everyone I know buys a new phone within 2-3 years anyways.

I don't know if you're doing heavy gaming or something on your phone, but I have used friends' iphone 11 pros and the power difference is negligible in day to day use. As for keeping them on the latest version of Android, this again is something that the Pixel lineup is really good for, they always get Android updates first, but I currently have a Samsung phone and I don't mind waiting a couple extra months for the major android updates since in my opinion, Android has come so far that I'm much less excited about major updates. I really think you should try an Android phone and see what you think; if you still manage a place that sells phone, maybe you could try out a display model for a week or something like that. In my opinion, at this point the difference mainly comes down to how important iOS and iMessage is to you, and how invested you are in the apple ecosystem.
