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.

Optimization · Practiced Mastery
Active dodge-heavy combat with a deep build system, tested against both scripted content and human opponents.

Execution · Practiced Mastery
Planning tactical approaches and executing careful shots where mistakes are lethal.
Guild Wars 2 leans Optimization (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.
Guild Wars 2
Dodge timing and active combat define moment-to-moment play
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.
Guild Wars 2
WvW and structured PvP feature real adaptive opponents
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.
Guild Wars 2
Loot RNG is present but secondary to skill expression
Tom Clancy's Ghost Recon Advanced Warfighter 2
Unknown enemy placements punish first attempts
Guild Wars 2 leans a little harder on optimization, though the gap is small.
Guild Wars 2
Build crafting and rotation theory-crafting reward deep analysis
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.
