Best way to transfer data from old Android to new one without losing stuff?

Just got a new Android phone (Samsung Galaxy S23), and I want to move everything from my old Pixel 4 without missing a beat. Tried using the Google backup and restore during setup, but some apps didn’t come back exactly as I expected—like game saves and some chat messages. Also, photos and videos are a must-have, obviously. I’ve heard about using third-party apps like Samsung Smart Switch or even manual transfers via PC, but not sure which is easiest and safest for someone who’s not a total tech wizard. Anyone tried these methods recently? What worked best for you without causing duplicates or missing data? Would love some step-by-step tips or warnings about what to watch out for. Any app recommendations or tricks to make this painless? Thanks!
