I've used Revolut, Monzo, Starling for both personal & business.
All of them have good apps, decent integrations, and better exchange rates.
Revolut seems strong right now with great exchange rates and some Premium features I use anyway so financially it makes sense.
Support has been tricky sometimes especially when they need documents.
I use a neo bank and I its really amazing, By the way, I am looking for buying research paper to my work. I also looking for it on internet, If anyone knows where I can get it then please let me know. I hope I will find it soon.
