head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Competitive PvP
Punch timing and counter prediction in movie-licensed boxing.

Execution · Competitive PvP
Twitch ball control plus constant prediction of human defenders on known maps.
Rocky Legends leans Execution (Competitive PvP); TagPro leans Execution (Competitive PvP).
TagPro leans a little harder on execution, though the gap is small.
Rocky Legends
Punch timing and blocking windows carry every exchange
TagPro
Ball handling, boosts and juke precision decide grabs
TagPro leans a little harder on reads, though the gap is small.
Rocky Legends
Human opponents feint and bait counters in versus
TagPro
Human defenders adapt to your routes every match
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rocky Legends
Little randomness beyond minor damage rolls
TagPro
Maps and power-up timers are fully visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Rocky Legends
Training allocation and counter knowledge are plannable
TagPro
Map routes, button plays and power-up timing are studyable
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.
