Two-year performance (base 100, in euros)
The difference is IUSQ's emerging-market exposure, which raises the number of holdings and slightly lowers the US weight. At the same cost, the choice is about coverage: IUSQ covers the world in one product; with IWDA you would need a separate emerging-markets ETF for the same exposure.
