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

Execution · Competitive PvP
Analog-stick boxing testing punch precision and counter-baiting against human opponents.

Execution · Competitive PvP
Twitch ball control plus constant prediction of human defenders on known maps.
Fight Night 2004 leans Execution (Competitive PvP); TagPro leans Execution (Competitive PvP).

Fight Night 2004
Versus humans, baiting counters and feinting is genuine prediction
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.

Outcomes follow inputs with little randomness
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.

Stat training and stamina management add a planning layer
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.
