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

Execution · Practiced Mastery
A destruction-driven military shooter where squads level buildings around objectives.

Execution · Practiced Mastery
Planning approaches with recon tools, then executing them under lethal fire.
Battlefield: Bad Company leans Execution (Practiced Mastery); Tom Clancy's Ghost Recon Advanced Warfighter leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield: Bad Company
Vehicle and infantry gunskill across big maps
Tom Clancy's Ghost Recon Advanced Warfighter
Lethal firefights punish sloppy aim and exposure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield: Bad Company
Predicting human squad pushes on objectives
Tom Clancy's Ghost Recon Advanced Warfighter
Multiplayer squads outflank and adapt to your habits

Destruction and large lobbies create chaos
Tom Clancy's Ghost Recon Advanced Warfighter
Enemy placements are scripted-but-unknown on first attempt
Tom Clancy's Ghost Recon Advanced Warfighter leans a little harder on optimization, though the gap is small.
Battlefield: Bad Company
Class roles and objective flow are learnable
Tom Clancy's Ghost Recon Advanced Warfighter
Drone recon, squad orders and approach planning decide missions
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.
