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.

Execution · Practiced Mastery
Massive persistent-war FPS where hundreds of players contest continents simultaneously.

Execution · Practiced Mastery
A pioneer of action-MMORPG combat where skill-shot execution and precise dodges are the primary test.
PlanetSide 2 leans Execution (Practiced Mastery); TERA leans Execution (Practiced Mastery).
TERA leans a little harder on execution, though the gap is small.
PlanetSide 2
Gunplay and vehicle piloting at FPS standards
TERA
Action combat with skill shots and iframe dodges is the core axis
PlanetSide 2 leans a little harder on reads, though the gap is small.
PlanetSide 2
Human enemies adapt, diluted across hundreds
TERA
Battlegrounds and large-scale PvP add a real but secondary reads layer
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
PlanetSide 2
Massive battles produce constant chaos
TERA
Gear enchanting RNG creates frustrating hidden-information variance
TERA leans a little harder on optimization, though the gap is small.
PlanetSide 2
Loadouts, terrain, and territory strategy matter
TERA
Class rotations and gear progression paths are extensively community-solved
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.
