Hmmm, I’ve never noticed what you mentioned on my recent phones. That said you should test a newer android yourself before making a purchase!
More of my personal experience… I have a Pixel 7 XL and a work Iphone which (edit) is an Iphone 12. Generally they are the same in terms of having no scroll lag or input lag at all. But, there is some lag on both when they are overheated, especially on the Iphone if I put it on a higher power charger (I trickle charge both when I can).
From a design perspective the biggest difference I notice is that my Pixel feels significantly smoother because of the 120hz display, and just the larger display in general. While I said neither of them have much lag, the Iphone feels noticeably less speedy. That said, I’m sure if you compared my Pixel to a high end Iphone results would be flipped. My work isn’t shelling out for whatever pro max stuff they sell (and neither would I!).
Beyond that, I can’t offer guidance. In my personal experience the Iphone UI is so frustrating that I can’t judge which one performs “better” or not, because only the Android feels comfortable to me. Between that and the lack of labels in some places (like the pull-down settings menu) it is impossible for me to daily drive the apple.
And a heavy duty three pack nonetheless! I didn’t realize packing factored into so many genders. Learn something new every day!
