Hello, I would like to add another ETF to my existing $VWRL (-0.65%) to my existing one.

I am currently wavering between: $EQQQ (-0.39%) & $XAIX (-0.67%) .

Or would you prefer something completely different due to the USA/overlapping of high positions?

Maybe someone here can help me with one and justify their opinion. Thank you & have a nice weekend.
