Does anyone know about the culture of different Lemmy instances?

I saw in this post that the culture between instances can vary quite a bit: https://lemmy.ca/post/40916774

What are the differences between the major instances?

For work browsing safety, my strategy is to use two instances:

• lemm.ee – because it doesn’t allow pornographic content.
• lemmynsfw.com – for anything I wish to subscribe to that falls into the opposite category.
