According to this page, ISIN does not depend of the exchange on which a security is listed. So if two funds are the same, then they should have the same ISIN.
ISIN is a key that uniquely identifies a security across the whole World. You can’t go wrong with ISIN.
Stock Exchange ticker is a key unique only in the scope of a given stock exchange. That’s why when you have Vanguard S&P 500 ETF traded on London Stock Exchange, the GBP version has a ticker VUSA, but the USD version has the ticker VUSD (the same for All-World: VWRL vs VWRD).
What you often see, is a ticker combined with the stock exchange key, which makes it then unique again. Like VUSA:LN (London), VUSA:SW (Swiss) etc.
