This is only a selling point in places like USA. Even before moving to the USA 13 years ago I was able to send money via wire transfer domestically for free, and it settled within 1 business day (to me that's fast enough). IIUC nowadays intra-EU wire transfers also are free (but I kinda view them as "domestic"), however I'm not sure how quickly they settle. The way how banking worked in the US was definitely one of the biggest culture shocks I've experienced when moving (and not in a positive way).
