I just went to a random front page thread on /r/homelab (a subreddit I know well) https://old.reddit.com/r/homelab/comments/1922ddn/since_no_o...

You can read for yourselves and see the difference between that and this.

Here's the same post as this on /r/aviation

For every reddit comment there R, you can find a distinct comment here H, such that H is worse than R.

There's just way more informed expertise on Reddit. The big advantage of HN is that some tech luminaries post here. But the overall quality is much lower than the topic-reddits. It's more like an /r/technology.
