I feel like the draw back of grapheneOs is basically no NFC payment and that the ui is a bit ugly at times (like the kind of weird gallery or the basic app symbols for standard apps)
And it is possible that some of your apps dont work, but personally i did not have had that issue yet.
you probably just have to test it.
But personally when i switched like half a year ago, i was rather positivly suprised. Everything just worked for me.
so i would suggest you to just try it out
