Hello, I would like to add another ETF to my existing $VWRL (+0.05%) to my existing one.

I am currently wavering between: $EQQQ (+0.04%) & $XAIX (+0.04%) .

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.
