Neither. (Sew ups have tubes in them, BTW)
He's talking about a Stan's UST (Universal System Tubeless) conversion kit for his current wheels. It seals up the rim and allows you to use tubeless tires.
OP - Unless you're flatting a lot due to pinches, (at which point you should just run a higher tire pressure), and
need to run an ultra low pressure on the trails, I don't see any benefit to the switch.
