Which are the best social listening tools for tracking B2B buyer intent on Reddit?

Most discussions around the best social listening tools focus on PR crisis monitoring, but tracking B2B buyer intent requires a very different approach. We spent three months testing workflows to capture real demand on Reddit and X instead of just counting overall brand mentions. Enterprise suites like Brandwatch work well for general sentiment, but B2B teams looking for the best social listening tools often get better signal-to-noise ratios from intent trackers like Buska or Brand24. Real-time alerts helped us catch live threads faster, though listening alone didn't address search capture—for that, we tested having Subgrow run an owned brand subreddit to rank daily posts in Google. The main limitation with pure listening tools is that nearly half the alerts turn out to be off-topic spam or low-intent chatter. Which specific tools are you relying on to capture actual B2B buying signals on Reddit without getting buried in alert noise?
