Sure but in my experience LLMs behave much more consistently than humans with regards to quality. LLMs don't skip tests because they have to make a deadline for example.

And now we have LLMs that review LLM generated code so it's easy to verify quality standards.

At the same time, the LLM will, with some reliability, ignore the patterns or best practices in your code, or implement the same thing twice in different ways.

There are certain things they do, or don't do, that a human typically wouldn't, putting absolutes and anecdotes aside

Humans, with reliability, will ignore the patterns or best practices in your code and implement the same thing twice in different ways.

In 25 years I've never worked in a codebase where this wasn't true.

As a group or the same person under the same constraints

It's far to nuanced for generalities tbt
