From my little understanding.....if I plan on playing fingerstyle/picking.....melody.....and never playing with anybody else.....that the low G is the way to go. On violin/mandolin I played mostly classical.....and only VERY (close to never) rarely with a piano accompaniment. Right now all I am doing is learning chords and playing some basic fingerstyle runs from the internet just to get my thumb/index/middle fingers coordinating a bit......and as with mandolin when I hadn't played in a long time.....the first week just to start getting the fingertips toughening up so I can practice more. Surprisingly (to me anyway).....the strings are at least as hard on my fingers as the mandolin was.....maybe harder. There seems to be plenty of gap over the frets though.....so I might get the files/sandpaper out and take some off the bridge. I am assuming taking it off the bridge is safer than at the nut? I can still remember starting up with the violin waaaaaay back in the 80's and with a cheap violin to begin with.....high action+cheap strings did give me some amazing tough calluses.
