For dev searches, Kagi. I switched during closed beta, and I couldn't be happier. The SEO'd GitHub or SO copypasta is gone by default, and it gives you the ability to ban or prioritize other sites in your searches. I honestly haven't had to do that much because their filters are great by default, though I did give MDN a bump so it's always at the top for web stuff.
be weary of astroturfing. Reddit has had this problem for over a decade and increasing popularity means more shills using the site to sway opinions. Aged accounts, karma boosting and fake comments/engagements are all common techniques to propagate a desired narrative
the problem with Reddit is for some stupid reason that has yet to be fixed and likely never will, Google shows reallllllly old reddit results but marks them as new.
I generally prefix search query with `site:reddit.com` or `site:news.ycombinator.com`
Which returns much better discussions about a question/topic, in those discussions can be genuinely great ideas and links
