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.

Reads · Grand Arena
A reads-heavy neutral game where V-System decisions and opponent modelling decide bouts.

Reads · Grand Arena
A neutral-focused fighter where managing the GRD gauge against an adapting opponent creates a constant strategic tug-of-war.
Street Fighter V leans Reads (Grand Arena); Under Night In-Birth II Sys:Celes leans Reads (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter V
V-Trigger combos and meaty setups require solid execution
Under Night In-Birth II Sys:Celes
GRD-boosted combos and precise Chain Shift timing demand real execution
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter V
V-System neutral game heavily rewards opponent habit exploitation
Under Night In-Birth II Sys:Celes
GRD tug-of-war with a human opponent is persistently adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Street Fighter V
No RNG; match flow is entirely player-driven
Under Night In-Birth II Sys:Celes
No RNG; GRD state is visible information
Under Night In-Birth II Sys:Celes leans a little harder on optimization, though the gap is small.
Street Fighter V
Season-by-season tier lists and V-Skill routing reward study
Under Night In-Birth II Sys:Celes
GRD management theory and optimal punish routing are well-documented
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.
