Pros
Pro Dedicated subreddits
Reddit has subreddits that function as dedicated forums to post all sorts of links, questions, images, news,... concerning the specific topic of the subreddit. A subreddit that's an alternative to gaming related questions on Slant would be /r/gamingsuggestions, where users can ask other users for game recommendations, based on the preferences they describe.
Pro Interaction
People who ask questions on Reddit can interact with people who respond through reply threads. That way the users can discuss the topic as much as they want to. Other users can up- or downvote users' suggestions, so that the best responses or suggestions are the first you will read.
Cons
Con Different subreddits even hold X as taboo while others would recommend it
The learning curve is steep to gouge the sentiment in the room of any such subreddit, if the plan is to go there as a main source of recommendations/opinion/info: it is less accessible vs. automated sites that utilize algorithms to centralize and rank products/services based on scraped data.
Con The question may be downvoted into oblivion
Reddit users are entirely free to up-or downvote posts on subreddits. It may happen that you are on a very popular subreddit and get confronted with some gratuitous downvoters very early on. If that happens, the post containing the question may disappear quickly from the first pages of the subreddit and never receive a proper response.
Con Noisy
Responses on reddit can sometimes be unnecessarily long or on the other hand just contain one word with no explanation. Some suggestions can be useless to the OP, but still receive upvotes. The reason for that is that users would often upvote those responses that they like most for themselves or think are funny.
