I have thor v2 with 3 230mm fans (front, side, top), and 2 slots for a 140mm.

So of the two fans, where do I place the better one......

1) the top rear exhaust?
2) the bottom intake (right next to PSU, air moving straight vertical)

I cant seem to figure out where.

I would use the better fan as an exhaust, because it will create a negative airflow environment sucking air in thus doing double duty.
Remember it is always easier and more efficient to pull a load than to push it even air.
 


While there are circumstances where negative airflow can be desirable, for most users under most circumstances a positive airflow will serve them better. Anyway, with the OP's setup, that 140mm will not be creating a negative airflow, only slightly reducing a positive airflow.
