When looking at hashing algorithms there's a whole lot of factors to
consider.
A few of the common considerations are:
1. performance.
2. cryptographic or not.
3. collision rate including avalanche effect and bit-size.
There are a bunch of other considerations but those are some high-level
concerns that will often come up when considering a hash function. In the
case of AES256 it is a cryptographically secure algorithm which often
implies a tradeoff in performance. Depending on your needs an alternative
algorithm might be more appropriate such as FNV (available in stdlib),
murmur, CityHash, etc that aren't cryptographically secure but provide
generally good hashing properties in terms of collision rate and
performance.
