"Table 7: Functional languages have a smaller relationship to defects than other language classes where as procedural languages are either greater than average or similar to the average."
"The data indicates functional languages are better than procedural languages; it suggests that strong typing is better than weak typing; that static typing is better than dynamic; and that managed memory usage is better than un-managed."

As for your un-sourced claim that "copying data is slower than not copying it", I'd suggest learning how immutable-first languages practice data sharing between objects to minimize the amount of copying needed.
