Be careful with Titanium backup. It cannot handle several modern Android things properly. (E.g. proper SE Linux file properties)

I learned the hard way after the fact...

It handled my recent transition flawlessly, but is there anything better?

Neo Backup and Swift Backup are my go-tos. First is free and open source, second is closed source and some features are locked behind paying but it's pretty cheap and feels more polished (only supports keeping one backup at a time though, unfortunately, and you can't browse backup files because they're forcefully encrypted).
