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

The sequel adding Horde mode to the campaign-plus-versus cover shooter formula.

Team arena brawls testing mobile combo execution and reading enemy engages.
Gears of War 2 leans Execution (Practiced Mastery); Naruto to Boruto: Shinobi Striker leans Execution (Competitive PvP).

Gears of War 2
Human opponents in versus drive prediction play
Naruto to Boruto: Shinobi Striker

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gears of War 2
Horde spawns add mild randomness
Naruto to Boruto: Shinobi Striker
Some matchmaking and map objective randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gears of War 2
Power-weapon timing and positioning are solvable
Naruto to Boruto: Shinobi Striker
Class loadouts and jutsu matchups reward study
