If you're not completely blind, you can notice both TS and PZ drop you somewhere in the middle of the sector map thing. Do they get more interesting the further you go to the edge? Do TS maps get even harder, do PZ maps contain more Artifacts? Or is it the same generation for the entire world and it doesn't really matter what part of the map I am in?

I don't know about Artifacts, but
some of PZ maps seem to be more interesting than others: https://knucklecracker.com/forums/index.php?topic=17338.msg123451#msg123451
