head to head
Blur asks more than Mario Super Sluggers, and the gap is execution.

Execution · Pure Mechanics
Arcade racing with Mario Kart-style power-ups bolted onto licensed cars.

Execution · Competitive PvP
Party baseball testing swing timing and pitch-guessing against friends under item chaos.
Blur leans Execution (Pure Mechanics); Mario Super Sluggers leans Execution (Competitive PvP).
Blur leans clearly harder on execution.
Blur
Racing lines and dodging shots demand car control
Mario Super Sluggers
Swing timing and fielding reactions decide most plays
Mario Super Sluggers leans a little harder on reads, though the gap is small.
Blur
Human racers bait and time power-ups against you
Mario Super Sluggers
Pitcher-batter guessing games against humans reward prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blur
Power-up pickups and incoming attacks add chaos
Mario Super Sluggers
Star powers and item errors inject party chaos
Blur leans a little harder on optimization, though the gap is small.
Blur
Track knowledge and pickup routes are learnable
Mario Super Sluggers
Team chemistry and lineup building are shallow but real
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
