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 · Grand Arena
Real-time strategy where hands, reads, and build optimization all matter at the top.

Execution · Grand Arena
A tag-enhanced Tekken that multiplies execution demands and opponent reads by adding partner management to every exchange.
StarCraft II: Wings of Liberty leans Execution (Grand Arena); Tekken Tag Tournament 2 leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
StarCraft II: Wings of Liberty
APM, macro, micro-control under pressure
Tekken Tag Tournament 2
Tag combos and partner launcher extensions demand high motor precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
StarCraft II: Wings of Liberty
1v1 ladder vs adaptive humans modeling you
Tekken Tag Tournament 2
Tag crash timing and incoming character reads against humans are constant
StarCraft II: Wings of Liberty leans a little harder on variance, though the gap is small.
StarCraft II: Wings of Liberty
map spawns minor; mostly known
Tekken Tag Tournament 2
No RNG; all information is visible
StarCraft II: Wings of Liberty leans a little harder on optimization, though the gap is small.
StarCraft II: Wings of Liberty
build orders, economy curves heavily solved
Tekken Tag Tournament 2
Tag team pairings and shared health management reward deep preparation
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.
