Why should traders from Stake.com or IG move to SWF for US Trading

Considering that Stake.com, IG.com, Etoro does not charge brokerage for trade - Is it worthwhile moving a US stock portfolio to Selfwealth?

- Stake.com has a smaller selection of stock based on their risk assessment and zero brokerage and one time fx transfer fees + other minor fees for services( US tax preparation, express money transfer and premium upgrades) https://***.com/pricing/
- IG.com has a much wider stock selection but no USD account and therefore multiple exposure to fx charges of 0.7% https://www.ig.com/au/share-trading/charges
- Etoro : Commission free and fx charges
