As you are asking this in a privacy community I would say Graphen. But as you want to keep gmaps you might also want the comfort you get with e/os when also using their cloud. Personally I would recomend a used pixel 8 with e/os and to try mapy.cz to replace gmaps. About going back to stock OS if you choose a pixel flashing images is stupid easy :) so no worrys there.

Bro uninstalled tiktok. Congratulations :)

I love that OP got more hate for using brave than tiktok :D . Anyway good job and happy degoogling :)
