Think that depends. For me, personally - yes - Starling is all I really need. The additional flexibility of the Revolut product may or may not have been worth the fiver paid - time will tell.
If you are more than a one man band though, the revolut account could be very useful.
Some years ago, I worked for a (dysfunctional) family-run start-up that provided some of the property information you (or your lawyer) needs when you buy a house or re-mortgage.
They employed several ‘agents’ to go out into the field to collect the data. These were dispatched with nothing but a mobile phone and a cheque book.
Back in the office there was the firm’s one-woman accounts team who could use the online banking but mostly wrote cheques to pay for stuff, including us.
The directors had the plastic and that was it.
Anything that could not be purchased by cheque was a pain or an expenses list waiting to run at the end of the month.
Issuing the field agents with a card for expenses would have meant that instead of running through reams of expenses claims, each agent would have been able to buy their own stationery, parking fees, congestion charges, local-authority fees without hassle - and all instantly auditable.
