Own both. Like both a lot.
Shadow is like hand to hand fighting as there are in tight shots. WhiteWater is like a drone war. Majority of shots are long with an open playfiled. Both have great flow.
Whitewater requires more strategy to capitalize and Shadow has cool innovations: BAttlefield, magnet into the lock, diverter control over the ramps.
Shadow has a wizard mode and WH2O a big bonus payoff. I would give Shadow the edge on animations and sounds.
I would have to give the edge to Shadow.
