If you haven't used either skip ahead and go for Graphene.  

Plan to stay away from apps that require the use of GooglePlayServicess.  Then you can ignore installing Aurora Store and or the Grapheme App for GPS.

An important lesson learned for me was, I tried to continue using apps that were Google dependant.  

Now, well, if it ain't in Fdroid or I can't side load it from a .apk I don't fuck with it.
