Fomo or Proof or Trust Pulse for active social proof?

Hey team,
Wanted to gain some insight on these three products? Has anyone used? If so, how was/is your experience?

On my platform, I have alot of artists registering for the platform and I would like to show IG handles of people signing up. Also when real estate developers visit the site, I want them to view and see how many artists are joining my network.

What if a platform like Upwork used this? Any value?
