Which is better, VUSD or IWDA?

Hi guys, I'm looking to buy and hold an ETF and currently deciding between VUSD or IWDA. Both of them hold similar stock profile, some might argue that IWDA tracks the world thus more diversify in their investment. VUSD only focus on the S&P 500 but most of the US company that VUSD invested are indeed international business too. Thus, I am not sure which one to choose. If based on the reinvesting dividend (IWDA) vs distribute dividend subject to tax (VUSD) which should i choose?
