Enterprise customers do not care about PKCS "standards" and don't as a rule really know much about password hashing. A good reason to use PBKDF2 instead of bcrypt is if your password hash needs to double as an actual key derivation function. Other than that, I can't think of any authentic good reasons to use it.

It doesn't matter, though. PBKDF2, bcrypt, scrypt: all fine. Just stop using salted, peppered, or lightly-battered hashes.
