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)

does anyone else agree with this?

farcaster has more of a builder community 

lens has more of a creator or content community

this is how I've described the difference to people who've asked about it on twitter 

they're also the only two I use & care about (outside of bird app)
