head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
PaRappa the Rapper
Hitting button cues on beat is the whole game
Ragnarock
Precise two-hammer drumming keeps the longship racing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
PaRappa the Rapper
No opponent; teachers follow set lines
Ragnarock

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
PaRappa the Rapper
Songs are fixed sequences
Ragnarock
Charts are fixed and visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
PaRappa the Rapper
Freestyle scoring quirks for Cool rank
Ragnarock
