I love a good anecdote.
Of [reposts, replies, and likes] I'm more inclined to value the reposts - after all that is someone thinking the that post is valuable enough to send out to their own followers. That indicates a clear pecking order with LinkedIn > X > Bluesky > Mastodon. It's interesting that LinkedIn is a more singular leader on likes, it seems both higher itself and X is lower. I guess that means LinkedIn people are more eager to hit the like button.
