Are you serious? Even something that would be considered "bad" argon2 set-up is far better than anything that is based on SHA256.

Modern GPUs and ASICs can perform millions of SHA operations per second, even with a poorly configured Argon2, you reduce that massively.

You can't compare plain SHA256 with PBKDF2. PBKDF2 can take a million SHA operations to hash one password, if you configure it to (default is somewhere 10k to 1M).

If you were to leak your company database with 1 million customers and hashed passwords, there's some theoretical considerations to be made on resistance to GPU and ASIC cracking, practically you're in a pretty bad place whichever algorithm was used. ^^

P.S. Cryptography would have more weight if half the passwords weren't a variation of password2021 and hunter22.

But you can. It’s literally just N times the hash. Typically the number of iterations is chosen to be somewhat slow on the server that derives it. But a specially designed rig can execute this with extreme parallelism and speed.
