Another vote in favor of Wise - very easy to use, competitive rates. A lifesaver when first moving to the UK, before you can get a "real" bank account.
Only two drawbacks, depending on how you're using it:
1. Not the place to accumulate large amounts of cash: the insurance is a little funky (you'd almost certainly get your money back if Wise went bust, but it'd take longer). No interest. And don't even think about using their investment feature, PFIC nightmare.
2. Not the cheapest way of transferring money, particularly for larger amounts. That's Interactive Brokers, as far as I've been able to find. For a few hundred or even thousand dollars/pounds, the difference is negligible; Wise can even be cheaper for very small amounts. But when you get to tens or hundreds of thousands (like buying a house, for example), then IBKR becomes significantly cheaper, even if it is a bit more of a hassle. Good step-by-step instructions here (not my blog):
