Unsure about the Q.Score, but for large data, MeowHash appears to also be a solid choice for non-cryptographic hashing: https://mollyrocket.com/meowhash

meow is certainly not solid. it's brand new and still being discussed.

regarding the "extremely fast" claim: it's only fast for large blocks, not for normal strings. it's the perfect hash for a file or block digest, certainly not for a hash table.

According to the developer the upcoming release will be faster even for small blocks

XXHash has made pretty decent inroads and is integrated into many products already, we use it for Geohashing at scale on Spark and can't fault it!

Meow requires several instructions that make it difficult to use in practice for a while.
