I can second the problems with Revolut. Weird and dodgy, and they spend every second of your use of their app trying to sell you shitty addon services like mobile phone insurance.

Starling, however, has been magic. I swapped my primary banking over to them and the only issue I've had is their dislike of rooted phones. That's only a minor inconvenience every few months when I forget to upgrade Magisk before the Starling app, though.

Transferwise I've used many times to transfer money for larger purchases in Europe. No complaints, but haven't tried the banking side of it.
