If you want updates like google pixel devices I think it's better to switch to that since updates have been a slow process for samsung devices. Once they roll out the update for your device you will have it. But you would need a lot of patience for that to happen.
pixel devices are the product of google itself only who makes the android updates. If you'll go for samsung flagships then you'll get the monthly updates otherwise it is not possible to provide monthly updates to mid range devices
