Personally - I went from Samsungs (for years - back before smartphones) to Pixel. Samsung used to be one of the best (Motorola used to be the best), but things change, and I prefer Google's tech support, I prefer their unlockable bootloader, I prefer their making the OS available online (and you can flash it without wiping the phone) - a lot of things. (For instance, I had one of their software developers assigned to work on a particular problem I was having - try to get that with Samsung.)
