head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
Tests arcade sports timing in a licensed fantasy sport with swingy Snitch catches.

Execution · Practiced Mastery
A grid-based bomber where reading human opponents' placement decides multiplayer matches.
Harry Potter: Quidditch World Cup leans Execution (Practiced Mastery); Super Bomberman R leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter: Quidditch World Cup
Timing passes, tackles and Snitch chases needs moderate dexterity
Super Bomberman R
bomb placement and dodge timing
Super Bomberman R leans a little harder on reads, though the gap is small.
Harry Potter: Quidditch World Cup
Versus a friend, faking plays adds light prediction
Super Bomberman R
human opponents can be out-predicted in placement
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter: Quidditch World Cup
Snitch appearances and combo opportunities add swing
Super Bomberman R
power-up spawn randomness
Super Bomberman R leans a little harder on optimization, though the gap is small.
Harry Potter: Quidditch World Cup
Special move charging and team choice reward system knowledge
Super Bomberman R
map knowledge and item-priority optimization
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.
