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.

Reads · Grand Arena
A controlled-pace fighter where resource management and opponent modelling outweigh raw execution pressure.

Execution · Grand Arena
A tag-team 3D fighter layering team optimization onto Tekken's execution and reads core.
Mortal Kombat 11 leans Reads (Grand Arena); Tekken Tag Tournament leans Execution (Grand Arena).
Tekken Tag Tournament leans a little harder on execution, though the gap is small.
Mortal Kombat 11
Kustom variation execution is demanding but more accessible than MKX
Tekken Tag Tournament
Tag combos and netsu juggles demand precise inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat 11
Fatal Blow timing reads and opponent tendency tracking are constant
Tekken Tag Tournament
Tag timing adds another layer of human mind-games
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat 11
No RNG; all mechanics are visible
Tekken Tag Tournament
Open information; nothing hidden between rounds
Mortal Kombat 11 leans a little harder on optimization, though the gap is small.
Mortal Kombat 11
Fatal Blow baiting, Kustom build selection, and frame data extensively studied
Tekken Tag Tournament
Team synergy and tag combo routing are optimizable 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.
