im a big fan of most sports, but i much prefer rugby union/afl/soccer to league. league players are pretty fit and you see some cool plays, but i personally find it really boring watching tackle > tackle > tackle > tackle > kick, tackle > tackle > tackle> tackle > kick, for 40 minutes. with once every 10 minutes someone finds a gap or someone catches a kick. on the other hand i do love watching union, seeing 30 phase defending and people jumping over the top and pushing through tackles and shit makes it really interesting. plus the viability of kicks and having proper lineups really makes it alot more fun to watch in my opinion. in terms of viewer enjoyment for me it would have to be soccer > union > afl > league. also the fact that union is properly international with things like the rugby world cup etc. make it super cool for me.
(im victorian btw and grew up here if that influences anything)
