The Bronstein Larsen is a little bit more agressive and leads to more dynamic postions but the endgame is slightly better for white due to the pawn structure i recommend instead of playing 4.Nf6 playing 4.Bf5 which leads to more strategical games and very interesting attacks with opposite side castling.
way too much theory. there's also a trap with h4 then beginners often blunder their bishop away by playing e6 then g4 then in a few moves the bishop is cooked
in the modern, I usually take with the g pawn, as pawns capture towards the center
good luck not getting destroyed with a ruined kingside structure!
