Rugby league or rugby union?

Basic differences are the following : Union - 15 players, League - 13 players; League - the attacking team can be tackled 6 times by the defending team - and even if the attacking team is unable to reach the defending goal line and score within the 6 tackles, they have to turn the ball over to the other team. Then the other team goes into the attack until they can reach the opponents' goal line and score. In Union, there are unlimited tackles and no restricted moves. Both teams attack and defend. The points differ too. I.e. - Union try 5 pts, League try 4 pts; Conversion after a try 2 ponits in both cases; Field goal or drop goal while in play - Union 3 pts, League 1 pt; Penalty Kick- Union 3 pts, League 2 pts. Also in League, there are no line outs when the ball goes out during play - but in Union there are Lineouts; Scrum - Union - 8 player scrum down, League - Ball is rolled over as in NFL. I prefer Union because of its continuity of play.
