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.
