This DLC was a bloody mess when it first came out but years later it's a solid addition of content.
The Leviathans are cool roadblocks that change the layout of the galaxy significantly just by existing and you get cool/powerful rewards for defeating them, especially with the release of the Archeology/Relic mechanic and the overhaul of the map generation in version 2.2

The various enclaves aren't as powerful as they used to be but they're still relevant and worth seeking out and add more options for acquiring resources and boosting your empire in various ways.

The endgame crisis added by the DLC isn't much of a muchness, it'll add more possibilities to the going ons of the lategame but it's a minor feature compared to the Leviathans and the Enclaves.

I'd recommend getting Utopia or Megacorp before Leviathans, maybe even apocalypse but it's still plenty good.
