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

Execution · Practiced Mastery
Planning tactical approaches and executing careful shots where mistakes are lethal.
Battlefield: Bad Company leans Execution (Practiced Mastery); Tom Clancy's Ghost Recon Advanced Warfighter 2 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 2
Accurate shooting under lethal fire still decides firefights
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 2
Multiplayer rewards predicting human positioning; campaign AI is scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Battlefield: Bad Company
Destruction and large lobbies create chaos
Tom Clancy's Ghost Recon Advanced Warfighter 2
Unknown enemy placements punish first attempts
Tom Clancy's Ghost Recon Advanced Warfighter 2 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 2
Squad orders, drone recon and approach planning carry the campaign
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.
