What are other people's impressions of the difference between the cultural vibe in farcaster vs bluesky vs mastodon vs lens?

(I have my own answers but am very curious what other people's answers are)

Lens went downhill after airdrop twit.

But UI/UX is better, they are more mature and have different app running live from image to text to Video. 

Farcaster is scalling up, apps are in dev and community is more wholesome and alligned towards eth ecosystem. 

other two i havent used, yet. 

None is ready of masses.
