Actually using Titanium Backup you can restore user apps and data between different roms, what will get into trouble is trying to restore system apps between roms. Usually when you update an already installed rom your apps and settings will remain. As for s-on being safer that's not entirely true, while it may prevent you from flashing something that you shouldn't have it also limits some of your recovery options if things go wrong. Read up and if you're unsure of anything just ask away. Good luck, OB
