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)

I'd say culturally mastodon and farcaster are similar as in the users care about some level of decentralization/independence and they don't care much about influence and reach.

BlueSky seems to be mostly verified Twitter refugees.

Lens has attracted "the bad part" of crypto such as token farmers.
