Phind is better about linking sources. I've found that generated code sometimes points me in the right direction, but other times it leads me down a rabbit hole of obsolete syntax or other problems.
Ironically, if you already are familiar with the code then you can easily tell where the LLM went wrong and adapt their generated code.
But I don't use it much because its almost more trouble than its worth.
Imagine a company with the power to break half the worlds computers with a business decision.
