Segments or discrete GPIOs for multiple strips

Right, i'm working on an install where i have 6 different strips (2 of them ran continuously).

Looking at the data wire routing, and i cant find much info on the pros/cons/difference between sharing 1 or 2 data wires and split them as segments, or running 5 or 6 individual data wires and set it up as a multistrip affair

Anyone got any views on the advantages or otherwise of one set up over the other?
