Features like Dual PIN or the revolving CVC are really nice and strong arguments for using bunq.
Setting a secondary PIN
Also, things like using my card with a group of friends by setting a secondary pin linked to a separated IBAN topped up by easy to track requests thrown in a WhatsApp group is gold.
One card to rule them all!!
I seriously dislike wallets. And keys but that's another story :). The fact that I could have just one card and swap it between my own, my company and my shared accounts was all the incentive I needed. From 8 to just 4 cards in my wallet
Instant push notifications
The bunq debit mastercard (bunq premium) allows me to pay online with international merchants but instead of the amount that I've spent being deducted from my bank account at the end of the month, every payment is immediately deducted and visible in my account. Also you get push notifications for all payments if you want.
