Tiktok may have an interesting algorithm but it certainly has a different crowd and culture of what to post than other platforms.
FB: Boomer, Gen-X, Older Millenial -- sharing stuff with friends and family.
Insta: Millenial and Gen-Z -- visual story telling.
TikTok: Gen-Z -- entertainment.
I'm from the BBS days, and I use FB for the Groups. Insta/Tiktok don't really have groups.
