head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, 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.

Optimization · Practiced Mastery
A narrative-heavy MMORPG where class rotation optimisation matters in raids and PvP warzones.
Guild Wars 2 leans Optimization (Practiced Mastery); Star Wars: The Old Republic leans Optimization (Practiced Mastery).
Guild Wars 2 leans a little harder on execution, though the gap is small.
Guild Wars 2
Dodge timing and active combat define moment-to-moment play
Star Wars: The Old Republic
Operation combat has moderate GCD management and positional demands
Guild Wars 2 leans a little harder on reads, though the gap is small.
Guild Wars 2
WvW and structured PvP feature real adaptive opponents
Star Wars: The Old Republic
PvP warzones feature real adaptive opponents
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Loot RNG is present but secondary to skill expression
Star Wars: The Old Republic
Gear drop RNG is present but secondary to ability knowledge
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Guild Wars 2
Build crafting and rotation theory-crafting reward deep analysis
Star Wars: The Old Republic
Advanced class ability rotations and set bonus builds are solvable
