This is quite an interesting question, because I believe there's two facets to the surface of the question.

Given you're interacting with a competent hacker (i.e. a person who is into tech not for money and for tinkering), you can't impress them. You can pique their interest, they may praise you, but if they are informed enough, anything looking like magic can be dissected easily. So technical excellence is meaningless.

Given you're interacting with a competent hacker again, everything technical will be subjective. Creating is deciding trade-offs all the way down and beyond. Their preferences will probably lay at a difference balance of trade-offs. Even though you catch "objective" perfection, even this perfection has nuances (see USB audio interfaces. They all have flat response curves, but they all sound different, for example), hence, technical excellence is not only meaningless, it's subjective.

On a deeper level, a genuine person who knows its cookies well, even though with gaps is a much more interesting and nicer person to interact with. They'll be genuinely interested in talking with you, and learn something from you, or show what they know gently, so both parties can grow together. They might not be knowledgeable in most intricate details, but they are genuinely human and open to improvement and into the conversation itself, not to prove themselves and win a meaningless battle to stroke their own ego.

An LLM generated response is similar. It's lazy, it's impersonated, it's like low quality canned food. A new user recently has written an LLM generated rebuttal to one of my comments. It's white-labeled gibberish, insincere word-skirmish. It's so off-putting that I don't see the point to reply them. They'll just paste it to a non-descript box and will add "write a rebuttal reply, press this point". This is not a discussion, this is a meaningless fight for internet points.

I prefer genuine opinions, imperfect replies, vulnerable humans at the other end of the wire. Not a box of numbers spitting out grammatically correct yet empty sentences.
