Very good, low fees and good exchange rates
Have been using Wise for a couple of years. Works very well - keeping and sending multiple currencies is easy and transfers are usually received quickly - often almost instantly.  If you are in a country where banks are generally terrible (France) you really need something like this. Exchange rates are much better than the banks give you and fees are very small.  You can also split your account into a personal and business account. Customer service I have found to be quite good, someone helped me quite promptly to work out the best way to send CHF for example.
