Pixel Pro is 120 hz whereas iPhone 12 is 60 hz only. Didn’t you feel it to be slow though not actually slow but because of half refresh rate. I am an iPhone 12 user from last two years and love every bit of it but just the refresh rate pushed me to buy s22 when it came on sale 2 weeks ago here. It is such powerful device with double the storage of my IP12 and double the refresh rate. Gboard on Android is a typing treat to hands. Having said that I keep using my IP12 every now and then as some of the things works much better there, like Apple Pay, Airpods, Hide my email, Ask App not to track. I know you will say it’s Apple ecosystem not iPhone itself which keeps pulling me back and I would agree. That’s why Apple doesn’t care to give as many features as Android makers because it gives the ecosystem which is enough pull. However some features of S22 are either not fully there on Apple like scrolling screenshot or don’t work as smooth like generating QR code for my WiFi. But if you bring Face ID into discussion, I will totally give in in favour of Apple. There is absolutely no match and I accept notch just for Face ID wholeheartedly. In short, both worlds have many good things for you. What is more useful decides what you use more.
