We are trying to decide if it is better to set-up a Vendor master for each country where we have off

We are trying to setup the Vendor master for the AP system. Is it better to have vendor master within a single SETID that can be used by all other SETIDs that are local or foreign OR is it better to setup a vendor master for each country separately (under a SETID for each country)? I know that it is possible to implement both options within PeopleSoft. I am trying to find out what most users within a multinational entity are doing in this regard. What are the pros and cons of each option?

For example, right now, we have a SETID, lets call it SETID A, that is setup for USD and we have another SETID, lets call it SETID B, that is setup for GBR (pounds). Now we have to setup another 13 or 14 countries. So we are deciding is it better to point all users to SETID A and they can just select the relavent country at the time of address setup and/or payment OR is it better to setup separate SETIDs for each of the 13 or 14 countries, which would be pre-setup with the correct currency for the
