Building comparison
head to head
Quake 4vsTom Clancy's Rainbow Six: Vegas
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Quake 4
Execution · Pure Mechanics
Fast arena-style shooter mixing a scripted Strogg campaign with twitch multiplayer.
Tom Clancy's Rainbow Six: Vegas
Execution · Competitive PvP
Tactical gunfights testing aim, entry planning and prediction of human opponents online.
Quake 4 leans Execution (Pure Mechanics); Tom Clancy's Rainbow Six: Vegas leans Execution (Competitive PvP).

Axis by axis
Execution8 vs 7
Quake 4 leans a little harder on execution, though the gap is small.
Quake 4
Aimbot plus strafe-jump inputs dominate both campaign and multiplayer
Tom Clancy's Rainbow Six: Vegas
Aim and snap-to-cover gunplay punish slow hands
Reads5 vs 5
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Quake 4
Multiplayer duels reward predicting human positioning and timing
Tom Clancy's Rainbow Six: Vegas
Multiplayer angles and pushes demand reading human opponents
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Quake 4
Spawn and item timing add mild uncertainty
Tom Clancy's Rainbow Six: Vegas
Terrorist hunt spawns vary modestly between runs
Optimization4 vs 5
Tom Clancy's Rainbow Six: Vegas leans a little harder on optimization, though the gap is small.
Quake 4
Item control routes and weapon picks are learnable
Tom Clancy's Rainbow Six: Vegas
Room-entry planning and map knowledge are studyable
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.
