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

Execution · Competitive PvP
Classic fighting execution and human prediction atop a famously unbalanced roster.

Execution · Competitive PvP
Twitch ball control plus constant prediction of human defenders on known maps.
Mortal Kombat Trilogy leans Execution (Competitive PvP); TagPro 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.
Mortal Kombat Trilogy
Dial-a-combo inputs and run-meter pressure demand fast hands
TagPro
Ball handling, boosts and juke precision decide grabs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat Trilogy
Human opponents must be baited into unsafe moves
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.

Mortal Kombat Trilogy leans a little harder on optimization, though the gap is small.

Knowing the bloated roster's broken tech is half the battle
TagPro
Map routes, button plays and power-up timing are studyable
