This discussion has happened before.

But I'll explain the conclusion here for your benefit.

BUG_ON() is a statement and everything inside of it will

BUG_ON() is always preferred because it allows arch
specific code to pass the conditional result properly
into inline asm and builtins for optimal code generation.
