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

Execution · Competitive PvP
The foundational test of fighting-game execution and human prediction at speed.

Execution · Competitive PvP
The 3D fighting series opener where execution and human mind-games decide every round.
Street Fighter II' Turbo leans Execution (Competitive PvP); Tekken leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter II' Turbo
Charge timing and anti-air reactions at turbo speed
Tekken
Frame-tight inputs, juggle combos, movement demand trained hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter II' Turbo
Fireball-trap mind games against an adapting human are the essence
Tekken
Human opponent adapts; throws, lows, sidesteps form mixup mind-games
Tekken leans a little harder on variance, though the gap is small.
Street Fighter II' Turbo
Twelve public movesets, nothing hidden
Tekken
No hidden info; only matchup unfamiliarity early on
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter II' Turbo
Matchup theory and spacing fundamentals were codified here
Tekken
Frame data, punishes, and combo routing are studyable systems
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.
