The 15% US WHT is L2 withholding, applies to all US-domiciled ETFs (for Swiss residents).

Regarding the cost comparison tables, I was referring to [Splitting the world: creating tax-advantaged global stocks portfolio using funds in 3a account - #7 by Dr.PI](https://forum.mustachianpost.com/t/splitting-the-world-creating-tax-advantaged-global-stocks-portfolio-using-funds-in-3a-account/7001/7).

Some countries have lower L1 withholding when held by US-domiciled ETFs. If you have a particularly high allocation to these countries, a US ETF may be better. However, the difference is very small on average for ex-US.

The tables unfortunately don’t contain All-World ex-US (yet).
