Now that’s an interesting proposition.
Santander makes me some money every month, I “like” Nationwide (and I might want to use their packaged account again soon), I need to deposit cheques regularly, so Starling is useful. And with Monzo, that’s the four banks I use, and of the four, Monzo is bottom of the list in terms of usefulness.
PS Sounds like a subject for one of @Peter_G polls.
