Ranked is just fun for me:
Turf war and Splat zones have my nostalgia, back when the game itself and ranked mode was brand spankin' new.
Then I hated loved Tower control as it was to dang complicated for my small mind probably has my craziest win streaks.
But rainmaker is definitely my favorite, simply because the objective can be taken almost anywhere on the map.
It is tower control, but YOU set its speed and path. Also dem tornadoes <3
