Honestly, I'm skeptical of the whole Keccak-derived ecosystem. The reduced-rounds variants like K12 and TurboShake are trading a conservative security margin for speed, which kinda feels odd when compared to BLAKE3. Meanwhile, BLAKE3 covers everything for real-world use. It's super fast on any input, fully parallelizable and has a built-in key mode. The only real advantage Keccak-based functions seem to have is standardization and potential hardware acceleration.
If you care about speed, security and simplicity, and you don't care about NIST compliance, BLAKE3 is hard to beat.
