Which should you buy?
These two are nearly even on the Mars Score (52.1 vs 51.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Core i5-14600K if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are cinebench r23 (multi).
Pick the Core Ultra 9 285H if you care most about tdp and cores. Its strongest claims are tdp, cores, boost clock.
Both ship with comparable l3 cache, so those specs don't separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
