Perseverance wins by every modern measure
Perseverance is more capable than Curiosity on every dimension: more instruments, better cameras, sample caching for eventual return to Earth, and MOXIE oxygen production. But Curiosity's 13+ year operational record on Mars is extraordinary — it outlasted its design life by 10 years. Perseverance wins the comparison, but Curiosity's longevity is the more remarkable achievement.
Perseverance is better for
scientific capability, sample collection, and oxygen production research
Curiosity is better for
longevity and operating beyond design specifications — Curiosity still holds that record
