It doesn't matter, though. xxhash is better than crc32 for hashing keys in a hash table, but both of them are inappropriate for file checksums -- especially as part of a data archival/durability strategy.

It's not obvious to me that per-page checksums in an archive format for comic books are useful at all, but if you really wanted them for some reason then crc32 (fast, common, should detect bad RAM or a decoder bug) or sha256 (slower, common, should detect any change to the bitstream) seem like reasonable choices and xxhash/xxh3 seems like LARPing.

CRCs like CRC32 were born for this kind of work. CRCs detect corruption when transmitting/storing data. What do you mean when you say that it's inappropriate for file checksums? It's ideal for file checksums.
