To be fair, these two are hardly comparable. Reddit is very toxic for sure but if you're looking for serious information or thoughts, it's still has some of that left. Whereas TikTok is pure entertainment, you're not gonna find anything "useful" or thoughtful there, but from the handful of clips (a couple dozen maybe) I've seen over the years it's indeed a delightful place to be, and my friends who do use it love it (more than Instagram at least).
