I enjoy both codes, as I'm an avid fan of the hurricanes, all blacks and the warriors. I enjoy watching a sublimely executed setplay by Daniel Carter or Carlos Spencer
At times I'd rather watch union, especially if i get to see a sweeping 90m try going through the hands of carter, umanga, rokokoko and howlett, but i'd probaly rather play league.
As with Johns Vs Larkham, they are different players who do different things for their teams. A more closer comparison would probaly be Lockyer vs Larkham.
