Those are fascinating, and give me a glimpse into a world I didn't even know I found interesting.
One major difference (that some may care about less than I do) is that the TikTok format is great for seeing a variety of content, but does little to help me create. Admittedly, YouTube is filled with lots of filler information (to please their own algorithms) but I could probably figure out what cameras/lights to use, software settings, how to edit, etc... The best TikTok can do is show me what others are capable of.
