Given BLAKE2 or SHA-3 running on 512 bits mode, faster hash will be break more easily than slower one. So BLAKE2 is the weakest…

On each case, you have to try at worst 2^512 times to collid, but the faster take less time to perform the full search.

Not considering known weakness, from 2 same output size hash function, the most secure is the slowest one.

And for internal checksum, there are better integrity check available, because safety is not the purpose, error detection is.

And for just error detection, you don’t care about 512 bits output, CRC32 is much faster. Or hamming matrix for error correction.
