Actually I think there’s an important distinction there: the draw of TikTok isn’t people sending videos to you, it’s the algorithm that automatically suggests them to you. I’ve heard it describes as uncanny at matching your interests and Reels isn’t anywhere near it.
(I don’t use TikTok so I don’t know first hand!)
I tried it once. It uncannily picked up on what I was interested that day. However, by the second day I had moved on to new interests, but it didn't. It keep trying to push the same thing as the day before that I was no longer interested in anymore.
Perhaps the algorithm has gotten better since, but I had no reason to want to use it after that.
I’ve used both and I think that’s cope. There’s more younger creators and maybe more varied content on TikTok.
If you want proof, watch someone’s feed with them. Invariably they will start to apologize. Classic “he’s different when we’re alone” rationalization for an addictive substance
