Have been using GrapheneOS for over a year now. With the Google compatibility layer I can use all my banking/credit card apps (4 different ones) and many more. I like the details available online and the frequent updates. Pretty smooth first installation too using their web installer and getting help on via their Matrix rooms or forum is usualy quick. I only have one government app where QR scanning doesn't work but not sure why. All other apps with QR scanning, including banking apps, work.
