What to look out for
The classic S&P 500 duel in Europe. Essentially a tie: same index, same 0.07% cost, full physical replication and Irish domicile for both. CSPX is the larger and older with huge liquidity; VUAA carries the Vanguard name and is equally solid.
In practice the choice usually comes down to which one your platform offers more cheaply and on which exchange. Their long-term returns are practically identical.
