head to head
Call of Duty: Modern Warfare 2 asks more than Superfighters Deluxe, and the gap is optimization.

Execution · Competitive PvP
Blockbuster 2009 sequel famous for killstreak chains and frantic multiplayer.

Execution · Competitive PvP
Frantic small-arena duels testing reflexes and prediction of human opponents.
Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP); Superfighters Deluxe leans Execution (Competitive PvP).
Call of Duty: Modern Warfare 2 leans a little harder on execution, though the gap is small.
Call of Duty: Modern Warfare 2
Fast time-to-kill rewards raw aim and reflex
Superfighters Deluxe
Aim, blocks, throws and movement decide frantic small-arena fights
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
Superfighters Deluxe
Human opponents constantly adapt positioning and weapon timing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Modern Warfare 2
Spawn flips and killstreak randomness
Superfighters Deluxe
Random weapon spawns and destructible chaos shuffle fights
Call of Duty: Modern Warfare 2 leans clearly harder on optimization.
Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
Superfighters Deluxe
Map knowledge and weapon priorities are a thin layer
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.
