The $VWRL is more broadly diversified (approx. 1400 vs. approx. 3600 companies). The $VWRL does not have quite as high a US share (68% vs 60%). The TER is similar (0.20% vs 0.22%). The gain over the last 365 days is identical except for the second decimal place (+ 3.76%).
Go with your preferences. If you are more focused on the US market and the technology sector, you would be better off with $IWDA. If, on the other hand, you would rather have a broader positioning and keep the US share somewhat lower, the $VWRL is probably better.
