undoubtedly they’re very highly trusted …
but also terribly expensive in dealing costs, with spreads of up to 1.5 pips (regularly) on EUR/USD
of the ones mentioned in the OP i would choose Oanda by far (i have used them on and off for more than 20 years, they are well regulated and honest, have great trading platforms available, and i trust them completely) - with Oanda, in my opinion, you don’t need to be too concerned about the legal stuff - they’re honest and good (and properly regulated, of course)
