@hedgehog don’t worry I am moving. I have decided to have US investment with IB and keep Swissquote for emerging market
But I try to always give full info to offer the possibility to do run the numbers 
To give another exemple, to have non-US ETFs with a US broker could be a “not so good idea” as dividends will be taxed at 15% which can be reimbursed by swiss tax authorities. However, you will have to wait few months to more than a year to be reimbursed.
