I had the original pixel XL then switch to samsung s21 and now im on a pixel 7 and I can say with out doubt the the pixel 7 is way more responsive and feels so much faster then any samsung phone I have ever used. Samsung puts a lot of spyware bloatware crap on there phones. if you hook a samsung up to adb and have a look at the list of apps that are spying on you its insane, all the apps listed in the settings on the phone are not all the apps installed. lots of hidden apps running in the background. Something that would piss me off was every update installed a bunch of apps i never wanted and had removed previously. I have recently installed grapheneos and its amazing and seem less, I could install it on my moms phone and it would not be a problem. works just like any other android phone except google play is locked in a cage and can only do what you allow it to. I have google play services installed but basically took all its permissions away, so that the camera app and the few other apps that look for it are not bothering me about it. google play services never connects to the internet on my phone.
I will never go back to a samsung phone, I love the stock android experience its simple and no fluff.
