I've only heard of GrapheneOS (and that authy is insecure in the same breath, so I need better 2fa apps). The biggest thing I can think of that I don't want to lose is the Motorola gestures. I *constantly* chop to open my flashlight and twist to open my camera. Besides that, I have never touched the rom before, and I have both wells Fargo and discover banking apps I use semi-regularly. The banking apps I could probably move to just doing their actions on the website, but that difficulty is something I would like to be aware of going in. I also use Mihon (successor to Tachiyomi) so problems with that and solutions would be nice.
