I was doing a sizable transfer a few weeks ago for a medical procedure and was having problems with wise. I tried XE and set up a transfer after connecting to my bank. I didn't pull the trigger there because the wise transfer finally got processed. I got a few emails from XE offering to help me get it done. Eventually I told them to piss off. Here's there response to that one.
Since they're now permanently giving me a better rate, i will definitely be giving XE a look next time.
