Verbatim DVD-R 8x. These are great, especially in a Pioneer 111 and they have a long life expectancy.
Also, you listed TY value line 8x - even if it was premium I would still choose the Verbatim 8x but value line is value line for a reason (it’s not as good lol). The 16x TYG03 aren’t the best IMO - they can often produce rather average burns. Verbatim 16x media can also be a little variable at times too, you would hope not to get a bad batch. Ridata is just shit.
So there’s the reasons you should go with 8x -R Verbatim.
