Just go to the Development section and pick a TW ROM on 4.3. They are prerooted.

Thanks for the suggestion! I should mention that I'm having issues with ROMs and I want to eliminate as many variables as possible by going stock, or as close to stock as possible, so that isn't working out for me...
If you want stock then just use Odin a 4.4.2 tar file. But if the 4.3 ROMs aren't working out its mostly user error. Are u clean flashing each ROM? Are you flashing gapps AFTER booting once on a fresh install. What errors or crashes do u get? Are you restoring apps using Titanium Backup? Make sure u don't restore any system apps. Just user apps.
