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.

Overwatch
Ult tracking, flanks, and baiting human teams
Overwatch leans a little harder on variance, though the gap is small.
Mortal Kombat 11
No RNG; all mechanics are visible
Overwatch
Minor spread and matchmaking noise
Mortal Kombat 11 leans a little harder on optimization, though the gap is small.

Fatal Blow baiting, Kustom build selection, and frame data extensively studied
Overwatch
Team comps, ult economy, and positioning theory
