Axis by axis
Execution5 vs 5
Even - both lean on execution about the same.
Reads0 vs 0
Even - both lean on reads about the same.
Variance3 vs 2
The Riftbreaker leans harder on variance: Wave timing and map resources add some unknowns
Optimization8 vs 7
The Riftbreaker leans harder on optimization: Base layout, tech tree, and defenses dominate survival
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
