In my opinion, it actually depend on what you are building honestly. TikTok can give you huge views on just one video overnight and next week everywhere could feel so quiet like nothing happened. YouTube Shorts look slower but I noticed that many people that actually subscribe there stick around even better. There as so many creators I discovered through Shorts months ago and I still watch their videos till today. My point is that algorithm doesn't have a permanent friend anyway, it changes every now and then. One minute they push your content, next minute it's like they have forget that your account exist.
