This is subjective, no? I have no clue which subreddits you frequent. I work in IT and as such follow a bunch of related subs. Those subs are perfectly fine if not helpful in a lot of cases. It depends on what you're consuming like..most things.
Like any Internet forum, of course it'll have its issues, particularly on the Reddit scale, but for the most part, I think it's pretty decent and I find it way better than most other 'social media' platforms.
